Baby Gap size charts for determining the correct size for your child. Shop Baby Gap on Swap.com.
Industry standard for baby apparel is to use age as the size, but it is important to measure your child as it is possible to have an older child that still needs a smaller size, or conversely a younger child that needs to size up. For example, a baby that is 12 months may still be wearing size 6 or 9 months given her measurements.
Baby Gap apparel in sizes up to 2 years accommodate extra room for a diaper. Measurements up to 2 years above are represented with a diaper on.
