Developmental Checklist - Birth to Age Three


The first three years of your baby’s life are very important. Infants and toddlers are learning to walk, talk, recognize people and do many other things. Parents are often the first to notice when their child is not learning or growing like other babies. This information outlines what to expect from your child during the ages from birth to three years old.

Some infants and toddlers may have trouble developing certain skills. If you have any concerns about your baby, call the Infant & Toddler Connection of Fairfax-Falls Church at 703-246-7121.

We’re here to help.

Answer Yes or No for each question.
