Activities That Support Development
Tummy Time Practice
Start with short sessions (3-5 minutes) multiple times a day. Place toys at eye level to encourage head lifting.
Face-to-Face Talking
Hold baby close and talk, sing, and make faces. This builds social connection and language exposure.
Rattle Play
Place a rattle in baby's hand and gently shake it. This encourages grasping and sound awareness.
Mirror Time
Let baby look at themselves in an unbreakable mirror. They will be fascinated by the face looking back.
Gentle Bicycle Legs
Gently move baby's legs in a bicycle motion to strengthen leg muscles and relieve gas.
Read Board Books
Hold baby and read simple board books with high-contrast images. It is never too early for reading.
When to Talk to Your Doctor
Every child develops at their own pace, and there is a wide range of normal. However, talk to your pediatrician if you notice any of these signs:
- •Does not respond to loud sounds
- •Does not follow moving objects with eyes
- •Does not smile at people
- •Does not bring hands to mouth
- •Cannot hold head up when pushing up during tummy time
- •Does not make any sounds
Early identification and support can make a significant difference. Trust your instincts — you know your child best.
