Your baby's development (4-6 months)

At 6 months, your baby should get their next health check from your child health nurse or family doctor.

Development

Around 4 to 6 months, most babies are learning new things:

• rolling over from their back to their tummy and tummy to their back
• making cute babbling sounds, giggles, or squeals
• moving and reacting to music and rhythmic sounds
• grabbing, holding and feeling things
• putting toys, fingers or objects into their mouth to feel and learn about them
• watching and listening to moving objects that make sounds
• enjoying games like peek-a-boo with you
• trying to sit up with some support
• grabbing their feet and even chewing on their toes.

You can help your baby learn and develop by responding to them during play.

Babies 4 to 6 months, on average, gain 100g to 150g per week. Ask your child health nurse or family doctor to record the head circumference, length and weight on their growth charts.
