What should a 3-to-6-month-old be able to do?

Between three and six months, your baby moves from watching the world to reaching out and joining it — and every reach, roll and giggle is a milestone worth celebrating.

In short

Between 3 and 6 months, most babies hold their head steady, push up on their arms during tummy time, begin reaching for and grasping objects, roll over, laugh and coo back when you talk, and turn towards sounds and voices. Milestones are a guide, not a deadline — babies bloom at their own pace. If something feels off or your baby seems to lose a skill, a quick developmental check brings reassurance.

What most babies are doing by this stage

Movement (motor)

• Holds head steady and upright when held, with good neck control by ~4 months
• Pushes up on forearms or hands during tummy time
• Rolls — often tummy-to-back first, then back-to-tummy nearer 6 months
• Brings hands together, reaches for toys, and grasps and holds objects
• May begin to sit with support by around 6 months

Communication & social

• Smiles back and laughs out loud (the social smile is well established)
• Coos, gurgles and makes a string of vowel sounds; begins babbling
• Turns head towards voices and interesting sounds
• Looks at faces, makes eye contact, and enjoys back-and-forth "chatting"

Thinking & senses (cognitive)

• Follows moving objects and people with the eyes
• Brings hands or toys to the mouth to explore
• Shows curiosity — looking at hands, reaching to touch and mouth things
• Recognises familiar faces, especially from a short distance

When a gentle check helps

Milestones arrive across a range of weeks, not on a fixed day. It is worth a friendly word with your paediatrician or a developmental check if by around 6 months your baby is not holding their head steady, not smiling or laughing, not reaching for things, not making sounds back to you, or seems very stiff or very floppy. Acting on any loss of a skill your baby once had is always worthwhile — early support is gentle, and the earlier it begins, the more it helps.

The Pinnacle way

A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under the care of a qualified clinician — never from an online list. If you'd like a baseline picture of how your little one is growing across movement, communication and play, our team can guide you warmly through a [developmental screening](/) and, where helpful, early intervention therapy. You know your baby best — your observations are the most valuable starting point.

Trusted sources

Aligned with CDC "Learn the Signs. Act Early." milestone guidance, the American Academy of Pediatrics and HealthyChildren.org, and WHO healthy-development resources — all of which frame these as typical ranges rather than fixed targets.
