Baby Development Milestones
Tracking your baby's development milestones is an important part of parenthood. Here are some key milestones to watch for:
| Age | Milestone |
|---|---|
| Newborn (0-2 weeks) | Making eye contact, smiling, and responding to sound |
| 1-2 months | Rolling over, reaching for objects, and cooing |
| 3-4 months | Sitting with support, babbling, and recognizing familiar faces |
| 6 months | Crawling, sitting without support, and understanding simple commands |
| 9 months | Standing with support, saying simple words, and pulling to stand |
| 12 months | Walking, saying a few words, and drinking from a cup |
These milestones can vary from baby to baby, so it's important to consult with your pediatrician if you have concerns about your baby's development.
