9 Months
Welcome to the 9-month milestone!
Your baby is on the move and exploring more than ever. Many babies at this age are crawling, pulling up to stand, and showing strong curiosity about their surroundings. You might hear new sounds as they practice communicating and see more personality shining through. This is also a key time for developing routines around sleep, meals, and play. Below, you’ll find helpful resources to support your baby’s learning, mobility, and growing independence during this exciting stage.

Concerned About Your Child's Development?
You know your child best. If your baby is not meeting one or more developmental milestones, has lost skills they once had, or if you have any concerns about their development, don’t wait, trust your instincts and seek support.
Start by talking with your child’s healthcare provider. Share your concerns and ask about developmental screening. Early identification and support can make a big difference.
