Frequently Asked Questions
What milestones should I expect in the first month?
In the first month, babies typically show reflexive movements, respond to sounds, and can briefly lift their heads while lying on their stomachs. Regular check-ups with a pediatrician can ensure the baby meets these early milestones.
When should my baby start crawling?
Most babies begin to crawl between 6 to 10 months. It is important to provide a safe environment for exploration as they gain mobility.
How can I support my baby's development in the first year?
You can support your baby's development by engaging in interactive play, providing a safe environment, and ensuring proper nutrition. The AAP recommends reading to your baby daily to stimulate language development.
What are the signs of developmental delays?
Signs of developmental delays can include not meeting milestones such as lack of social smiling by 2 months or not sitting up by 9 months. If you have concerns, contact your pediatrician for a developmental screening.
At what age can babies start solid foods?
Most babies are ready for solid foods around 6 months. The CDC recommends starting with single-grain cereals and pureed fruits or vegetables, introducing new foods gradually.
