What most babies do by this age:

- Smiles or laughs when you play peek-a-boo
Language/Communication Milestones

Tips and Activities: What You Can Do for Your 9 month old
As your baby’s first teacher, you can help his or her learning and brain development. Try these simple tips and activities in a safe way. Talk with your baby’s doctor and teachers if you have questions or for more ideas on how to help your baby’s development.
- Repeat your baby’s sounds and say simple words using those sounds. For example, if your baby says “bababa,” repeat “bababa,” then say “book.”
- Place toys on the ground or on a play mat a little out of reach and encourage your baby to crawl, scoot, or roll to get them. Celebrate when she reaches them.
- Teach your baby to wave “bye-bye” or shake his head “no.” For example, wave and say “bye-bye” when you are leaving. You can also teach simple baby sign language to help your baby tell you what he wants before he can use words.
