6 Months: Rolling Over and Finding Their Voice
At 6 months, many babies start rolling over and making a wider range of sounds as they explore more actively.
Social/Emotional
- Knows familiar people.
- Often enjoys looking at themselves in a mirror.
- Laughs.
Language/Communication
- Takes turns making sounds with you.
- Blows “raspberries” (sticks tongue out and blows).
- Makes squealing sounds.
Cognitive (Learning, Thinking, Problem-Solving)
- Puts things in their mouth to explore them more often.
- Reaches for a toy they want.
- May close their lips to refuse a food they don’t want.
Movement/Physical Development
- Rolls from tummy to back.
- Pushes up with straight arms during tummy time.
- Leans on their hands for support while sitting.
Caregiving Tip
As babies start rolling, their range of motion grows, so check the surrounding area for anything unsafe. Many families also begin solids around now, so it helps to watch head control and sitting readiness too.
When to Consider Talking with a Pediatrician
If your baby shows no attempt at rolling, doesn’t respond to their name, or doesn’t react to loud sounds, it’s worth bringing up with a pediatric provider. This information isn’t a diagnostic tool and doesn’t replace advice from a medical professional.
