Your Baby at 6 Months


How your child plays, learns, speaks, acts and moves offers important clues about your child’s development. Developmental milestones are the things most children can do by a certain age. Check the milestones your child has reached by the end of 6 months and talk with your child’s doctor at every visit about the milestones your child has reached and what to expect next.

Help Your Baby Learn and Grow 

What You Can Do for Your 6-Month-Old

You can help your baby learn and grow. Talk, read, sing and play together every day. Below are some activities to enjoy with your 6-month-old baby today.


  • Play on the floor with your baby every day.
  • Learn to read your baby’s moods. If he’s happy, keep doing what you are doing. If he’s upset, take a break and comfort your baby.
  • Show your baby how to comfort herself when she’s upset. She may suck on her fingers to self-soothe.
  • Use “reciprocal” play—when he smiles, you smile; when he makes sounds, you copy them.
  • Repeat your child’s sounds and say simple words with those sounds. For example, If your child says “bah,” say “bottle” or “book.”
  • Read books to your child every day. Praise her when she babbles and “reads” too.
  • When your baby looks at something, point to it and talk about it.
  • When he drops a toy on the floor, pick it up and give it back. This game helps him learn cause and effect.
  • Read colorful picture books to your baby.
  • Point out new things to your baby and name them.
  • Show your baby bright pictures in a magazine and name them.
  • Hold your baby up while she sits or support her with pillows. Let her look around and give her toys to look at while she balances.
  • Put your baby on his tummy or back and put toys just out of reach. Encourage him to roll over to reach the toys.
