Infant and Early Childhood Development

All babies develop at their own pace. It is important to make sure your child sees a pediatrician on a regular basis and gets the vaccines needed to stay healthy. Recommended screenings, vaccinations, and care can help make sure your child has the best start in life.

Well-Child Visits

Well-child visits are important doctor visits for your kids. Your child’s pediatrician will look at your child’s health for physical, emotional, and social development. Children will get a physical exam and vaccines as needed. During the first two years of your baby's life, there are several well visits to ensure your child is growing up healthy.

The recommended well-child visits are:

  • Newborn Visit
  • 1 Month Old (If Breastfeeding)
  • 2 Month Visit
  • 4 Month Visit
  • 6 Month Visit
  • 9 Month Visit
  • 12 Month/1 Year Visit
  • 15-18 Months of Age
  • 24 Month/2 Year Visit
  • 30 Month Visit
  • Ask questions at these visits. After your child turns 2 years old, well-child visits should continue once a year. If you need help finding a provider, visit


    Developmental Milestones

    During your child’s well visits, the pediatrician can tell you about your child’s development and let you know when to expect new milestones — like walking and talking. These are sometimes called “developmental milestones.” Every child learns at a different rate, so ask your pediatrician if you have questions.

    Review the below recommended childhood vaccines for a child's first two years.

    • A check ✓means that this is the earliest and best time for your child to be immunized.
    • If your child misses the “best time” for vaccination, he or she should still be immunized as quickly as possible.
    • Ask your doctor about getting your child caught up.
