Movement/Physical Development
Rolling, pushing up, supported sitting, and active grasping give your baby more ways to change their view and approach a goal. Notice how body parts increasingly work together rather than judging all movement by how long one position lasts.
Cognitive
Your baby learns through mouthing, touching, and repeating actions with objects, and may begin anticipating what comes next in a familiar routine. Safe exploration and your response to a discovered result help separate experiences connect.
Social/Emotional
Your baby more clearly recognizes familiar people and interaction patterns and uses smiles, sounds, and movement to keep a favorite exchange going. Shifting emotional states still depends heavily on an adult coming close, interpreting, and helping.
Language/Communication
Sound play and turn-taking may become richer. Your baby watches and listens to a speaker and tries to respond. You can imitate a sound, pause, and continue with real language instead of asking for one correct syllable.
How to use this page
Developmental Milestones are foundational reference points that Better Parenting has aligned with the level about 75% of children can do by this age. Whole-child development Skills come from Growth Paths across four Domains and 31 Sub-Domains. They offer further directions for growth beyond the foundation—not expectations that every child should already meet every item or be ahead in every Sub-Domain.
This page contains 18 formal Milestones drawn from the CDC and UNICEF resources linked below. Not observing one item yet is not, by itself, a reason to panic. Continue noticing it during ordinary care, play, and conversation rather than turning the page into a concentrated test.
How to read the historical status
The icons summarize Milestone Assessments submitted by Better Parenting parents:
- ✅ Observed for nearly all: fewer than 10% were marked not yet observed.
- 🆗 Observed for most: 10% to under 20% were marked not yet observed.
- ⚠️ Not yet observed for many: 20% to 40% were marked not yet observed.
- ⛔ Not yet observed for a large share: more than 40% were marked not yet observed.
The largest valid sample for a single Milestone on this page is 482 children. These historical product data help families interpret the page and help Better Parenting improve its content. They are not estimates for the general child population and cannot be used for diagnosis.
Movement/Physical Development
Foundational Milestones
Rolls from tummy to back
Gross Motor | CDC + UNICEF | 🆗 Observed for most
What to notice: In a safe, familiar setting, notice whether your baby rolls from tummy to back. Focus on the movement they initiate and organize, and provide the support the situation requires rather than moving their body through the action as a test.

Pushes up with straight arms when on tummy
Gross Motor | CDC | 🆗 Observed for most
What to notice: In a safe, familiar setting, notice whether your baby pushes up with straight arms when on tummy. Focus on the movement they initiate and organize, and provide the support the situation requires rather than moving their body through the action as a test.

Rocks back and forth
Gross Motor | UNICEF | ⚠️ Not yet observed for many
What to notice: In a safe, familiar setting, notice whether your baby rocks back and forth. Focus on the movement they initiate and organize, and provide the support the situation requires rather than moving their body through the action as a test.

Rolls over in both directions.
Domain: Movement/Physical Development | Sub-Domain: Gross Motor
What to notice: Does your baby try to roll toward people or toys on either side? Notice how the shoulders, trunk, and legs turn together, not only whether they eventually reach the toy.
How to support it: Rolling changes body position and helps your baby approach things they want to see or touch in different directions. What matters is using the new movement for exploration. Follow your baby's existing gaze, reach, and turning intention, offer safe opportunities on both sides, and respond to their attempts to get closer.
Keep in mind: Leave room for your baby to choose the direction instead of repeatedly moving a target beyond reach.
Explore the Gross Motor Growth Path
Responds to sights in the environment by orienting head or body to understand the information in the event. For example, a young infant will re-position their body to be picked up when seeing a familiar adult.
Domain: Movement/Physical Development | Sub-Domain: Gross Motor
What to notice: When your baby sees you reach out to pick them up, do they turn toward you, lean closer, or otherwise adjust their body? Unlike turning toward a sound, visible information is now helping the body prepare.
How to support it: Your baby is beginning to connect what they see with what will happen next and to prepare their body to participate. Make everyday signals for picking up, approaching, and interacting easy to see. Once your baby notices, leave a moment for a response, then continue based on what they do.
Keep in mind: The goal is to let visual information prompt an active adjustment, not to require imitation of a prescribed movement.
Explore the Gross Motor Growth Path
Coordinates hands and eyes when moving objects.
Domain: Movement/Physical Development | Sub-Domain: Fine Motor
What to notice: While moving an object they are holding, does your baby watch it and adjust the position or direction of the hand? Beyond simply holding on, notice the continuing hand–eye coordination during movement.
How to support it: Hand–eye coordination expands from the moment of reaching into ongoing action: your baby watches while moving and experiences how their movement changes an object's position. Offer objects that are easy to hold and whose movement is easy to see, and respond to discoveries your baby initiates so looking and moving stay connected.
Keep in mind: There is no need to prescribe a route or require accurate movement.
Explore the Fine Motor Growth Path
Uses single actions to explore shape, size, texture, or weight of objects, such as turning an object over or around, or dropping or pushing away an object.
Domain: Movement/Physical Development | Sub-Domain: Fine Motor
What to notice: Does your baby turn, push, or feel an object to encounter different parts of it? This skill concerns how the hands explore an object, not only where the object ends up.
How to support it: Texture, shape, and weight become familiar through real handling. Offer safe materials that are easy to grasp and provide different tactile experiences, respond to the action your baby is already taking, and occasionally demonstrate one new possibility.
Keep in mind: Allow repeated exploration of the same material rather than quickly turning it into a test of names or correct identification.
Explore the Fine Motor Growth Path
Shows increasingly refined grasps.
Domain: Movement/Physical Development | Sub-Domain: Fine Motor
What to notice: When your baby grasps something, are the fingers beginning to participate more actively, with small adjustments after the grasp? Notice changes in how they hold; precisely picking up a tiny object is not the expectation at this point.
How to support it: As grasping changes, the palm and fingers increasingly take different roles according to the target. Offer objects whose size and shape are safe and manageable, so your baby can experience the effects of different grips. Help only by placing an object within reach when needed.
Keep in mind: Practice should serve the wish to hold and play, not rely on forcing finger positions or introducing smaller, riskier objects.

Foundational Milestones
Puts things in her mouth to explore them
Exploration and Discovery | CDC + UNICEF | ✅ Observed for nearly all
What to notice: During familiar play or daily life, notice whether your baby puts things in their mouth to explore them. Leave time to respond and use what happens next as part of what you observe instead of repeating the situation until one expected answer appears.
Explore the Exploration and Discovery Growth Path
Reaches to grab a toy she wants
Reasoning and Problem-Solving | CDC | ✅ Observed for nearly all
What to notice: During familiar play or daily life, notice whether your baby reaches to grab a toy she wants. Leave time to respond and use what happens next as part of what you observe instead of repeating the situation until one expected answer appears.

Attends to quantity in play with objects, such as reaching or looking for more than one object.
Domain: Cognitive | Sub-Domain: Emergent Mathematical Thinking
What to notice: When more than one object is in view, does your baby keep looking or reach for another one? This shows attention to quantity, not yet an understanding of numerals or an exact comparison.
How to support it: Early number sense grows through direct experience: there can be another object beyond the first, and removing one changes what remains. Offer safe chances to notice several objects and respond when your baby looks for more.
Keep in mind: There is no need to turn this into counting practice or ask for a correct answer.
Explore the Emergent Mathematical Thinking Growth Path
Uses a variety of actions to examine people and objects, such as shaking, or dropping.
Domain: Cognitive | Sub-Domain: Exploration and Discovery
What to notice: Does your child use different actions with the same object and notice changes created by shaking, dropping, or another movement? Look for self-directed exploration rather than repetition of an adult-prescribed action.
How to support it: Different actions produce different feedback and help your baby discover how an object can be affected. Respond to what they notice, demonstrate one new action when useful, and then wait for them to try.
Keep in mind: Allow safe repetition instead of treating every shake or drop as misbehavior or assigning one correct use to every object.
Explore the Exploration and Discovery Growth Path
Engages in reciprocal imitation games, such as patting on a table or handing an object back and forth.
Domain: Cognitive | Sub-Domain: Imitation and Symbolic Representation and Play
What to notice: Does your baby notice your action and respond with a similar one, continuing a back-and-forth exchange? Look for mutual imitation, not an exact copy of a sequence.
How to support it: Back-and-forth imitation connects what children see with what they do and lets them experience the pleasure of being answered. Begin by copying a sound or movement your baby already makes, wait for them to notice, then add a small variation.
Keep in mind: Keep it participatory rather than turning the demonstration into a test.
Explore the Imitation and Symbolic Representation and Play Growth Path
Anticipates familiar actions or routines, such as getting picked up or being fed.
Domain: Cognitive | Sub-Domain: Memory
What to notice: Before a familiar care routine begins, does your baby respond in advance to your movement or the setting? The focus is an expectation formed through experience, not only becoming happy or calm after the event starts.
How to support it: Repeated, predictable interaction helps a child connect an earlier cue with a later experience. Keep cues during daily care clear and gentle, allow time for your baby to respond, and then continue. Notice what they already appear to expect.
Keep in mind: There is no need to add a separate memory test or deliberately disrupt routines to manufacture surprise.
Explore the Memory Growth Path
Modifies reactions (expressions and actions/behaviors) based on other people's responses.
Domain: Cognitive | Sub-Domain: Creativity
What to notice: After you respond, does your baby change their expression, sound, or movement to continue the interaction? Notice adjustment based on feedback, not whether they invent something entirely new.
How to support it: Interaction gives children immediate feedback and room to vary expression. Respond attentively to the signal your baby already offers, imitate it or make a small change, then wait.
Keep in mind: The goal is to make experimentation meaningful, not to keep entertaining until the baby performs or to treat repetition as a lack of creativity.

Foundational Milestones
Will recognize and respond to their name
Sense of Identity and Belonging | UNICEF | ⚠️ Not yet observed for many
What to notice: During a comfortable, familiar interaction, notice whether your baby will recognize and respond to their name. Understand the behavior alongside the people, feeling, and sequence around it rather than drawing a conclusion from one isolated response.

Further Skills for Whole-Child Development
Responds positively to familiar adults' efforts to help with stressful moments.
Domain: Social/Emotional | Sub-Domain: Relationships with Adults
What to notice: When uncomfortable or startled, does your baby respond positively to support from a familiar parent by moving closer, relaxing, or interacting? They do not have to stop crying immediately every time they are held.
How to support it: Consistent care helps children expect support during difficulty. Offer familiar, gentle help suited to the baby's state, observe what is effective, and adjust.
Keep in mind: Settling may take time; continued crying is not proof of a failed relationship, and comfort should not be withdrawn to test dependence.
Explore the Relationships with Adults Growth Path
Watch another child attentively when he/she is playing with a toy.
Domain: Social/Emotional | Sub-Domain: Relationships with Other Children
What to notice: While another child plays, does your baby keep attending to that child's actions and toys? Notice interest in a peer without expecting interaction, sharing, or joining yet.
How to support it: Observation helps another child's actions and reactions become familiar before participation. Offer safe, unhurried chances to be together, follow your baby's gaze with a brief response, and allow watching without acting.
Keep in mind: Do not force contact to make the children play or treat parallel attention as social failure.

Language/Communication
Foundational Milestones
Takes turns making sounds with you
Communicating and Speaking | CDC + UNICEF | ⚠️ Not yet observed for many
What to notice: During an ordinary exchange, notice whether your baby takes turns making sounds with you. Gaze, gesture, sound, language, and what happens next can all clarify the communication; avoid requiring the behavior on cue as a test.

Further Skills for Whole-Child Development
During face-to-face interactions, changes focus when familiar adults talk or sign about objects, people, or events.
Domain: Language/Communication | Sub-Domain: Attending and Understanding
What to notice: When the focus of communication changes, does your baby shift toward the relevant person or object? More informative than one look is whether attention can move with the shared exchange.
How to support it: Shifting attention during communication helps children connect what they hear with its referent. Make the cue clear and the pace unhurried, confirm that your baby noticed, then continue.
Keep in mind: Avoid rapidly pointing to several targets or physically turning their head to maintain participation.
Explore the Attending and Understanding Growth Path
Looks at pictures of familiar people, animals, or objects when an adult points at the person, animal, or object.
Domain: Language/Communication | Sub-Domain: Emergent Literacy
What to notice: When you point to a familiar person, animal, or object in a picture, does your baby shift their gaze to it? Following the point is meaningful; one look or a reach for the card does not by itself show recognition of the pictured object or print.
How to support it: Pictures become something two people can attend to together, while adult pointing and talk connect an image with familiar life. Point and name, then follow the baby's gaze, reach, or sound with a response.
Keep in mind: Make looking together meaningful before asking for identification without support.
Explore the Emergent Literacy Growth Path
Looks at familiar animals or objects when they are named such as puppy or ball.
Domain: Language/Communication | Sub-Domain: Vocabulary
What to notice: After hearing the name of a familiar object or animal, does your baby look toward it? Notice the name-to-object correspondence without requiring spoken use or recognition of a picture version.
How to support it: Object names gain meaning through repeated seeing, touching, and hearing. Name what your baby is already attending to, keep word and real object together, and respond when they search or look.
Keep in mind: Use the same word across contexts rather than relying only on fixed flashcard tests.

Common questions
Which age should I use if my child was born early?
For a child born more than 3 weeks early, the CDC recommends using corrected age when checking Milestones until age 2. Children differ, so you can also discuss the full pattern at a well-child visit.
