Frequently Asked Questions
What are the key developmental milestones for a 3-month-old?
At 3 months, babies typically can lift their head 45 degrees when lying on their stomach, track objects with their eyes, and begin to smile socially. These milestones are crucial for assessing their early development.
When should my baby start crawling?
Most babies start crawling between 7 to 10 months. However, some may skip crawling and go straight to walking. It's important to encourage tummy time as it strengthens their muscles for crawling.

Engage with your baby through talking, reading, and play. Providing a safe environment for exploration is key. The AAP recommends interactive play to foster cognitive and social development.

If you notice significant delays in reaching milestones, consult your pediatrician. The AAP suggests discussing any concerns about development during regular check-ups.
When do babies typically say their first words?
Babies usually say their first words around 12 months. Early language development can be supported by talking to your baby often and responding to their coos and babbles.
