Infant and toddler health

Babies seem to learn something new every day. And in fact, everything in babies' lives helps them learn more about their world. That includes cuddling before nap time and watching and listening to people around them.

As babies grow and change, parents often have new questions about infant health. How do I get a baby to sleep through the night? When do I give a baby solid food? When will a baby sit up? What are signs that a baby might be sick?

There are many ways to learn about infant health. Talk to your baby's health care professional. Use other sources, such as a phone number staffed by health professionals. Trust your gut, too. And know that timing is key to an infant's health. The earlier problems are found, the sooner treatment can begin.
