6-Month-Old Milestones: What to Expect
Six months is a turning point. The tiny, largely stationary newborn who needed everything done for them is becoming a person with opinions, a social presence, and a body that's learning to move with real intention.
Communication and Language
Most babies at 6 months babble using vowel-consonant combinations (ba, da, ma, ga), respond to sounds by turning toward the source, react to their name, recognize familiar voices, make different sounds for different emotional states, and engage in back-and-forth vocal exchanges with caregivers.
Worth a closer look: Very limited babbling, not responding to their name or familiar voices, no variation in vocalizations, or loss of sounds previously present.
Movement and Motor Skills
Most 6-month-olds roll in both directions, push up onto their hands during tummy time, begin sitting with support, reach for objects with both hands, transfer objects hand to hand, and bear weight through their legs when held standing.
Worth a closer look: Not rolling in either direction, not pushing up during tummy time, not reaching for objects, significant stiffness or floppiness, or consistent one-sided use.
Social and Emotional Development
Most 6-month-olds smile and laugh readily, show excitement when caregivers approach, enjoy interactive games like peekaboo, imitate facial expressions and some sounds, and show clear interest in watching and responding to people.
Frequently Asked Questions
Should a 6-month-old be rolling?
Yes. Rolling in both directions is expected by six months. If your baby isn't rolling at all at six months, a pediatric PT evaluation is appropriate.
Is it normal for a 6-month-old to not sit independently?
Most babies begin sitting independently closer to 7-9 months. Not sitting independently at six months is completely normal. Not sitting with support at all, or having very little trunk control, is worth discussing.
