My 9-month-old baby: learning to grab, bang, and throw

Your baby might be developing new skills including the ability to grab anything that is within reach. In addition, he might start shaking, banging, dropping, and throwing any item he can lift, so be careful. If your baby hasn't already, he might say "mama." However, some babies could go months longer before they start using new words. This is completely normal.

9-month-old baby sleep patterns and tips
  • Baby separation anxiety might keep your baby up at night again, but with a little patience on your part, your baby should be able to get back to sleep easier than before.
  • Daytime naps can help your baby handle teething more effectively by giving him a chance to rest if teething keeps him awake at night. Feeling rested can help him be more alert and active during the day, which might help him sleep better at night.
  • Have questions about SIDS?

    Learn about SIDS at the American Academy of Pediatrics.

Keep giving your 9-month-old baby new nutritious choices

Your 9-month-old baby continues to grow and develop, and needs the right foods and nutrients to maintain his health. Introduce new foods to your baby gradually and one at a time to determine whether he is allergic. If you notice unusual reactions during or after feeding your baby a specific food, discuss them with your health care professional.

In addition to mashed fruits and vegetables, here are some new foods to consider in addition to breast milk or baby formula:

  • Finger foods (lightly toasted bagels, cut up; small pieces of ripe banana; well-cooked spiral pasta; teething crackers; low-sugar O-shaped cereal)
  • Small amounts of protein (egg; pureed cooked meats, poultry, and boneless fish; tofu; well-cooked and mashed beans with soft skins, such as lentils, split peas, pintos, black beans)

Help your 9-month-old baby's cognitive development

Your baby has learned a lot in the last eight months; you can continue your baby's brain development in simple ways:

  • Read him books, naming and pointing to objects and people.
  • Teach him hand-eye coordination games such as "patty-cake" and "peekaboo."

  • Walk while holding on to furniture
  • Grab objects with his thumb and index finger
  • Wave "bye-bye"
