Items may not be offered in all sizes above. For best fit, use height measurement. Since all children grow at their own pace, this is the most accurate measurement. Weight should be considered when a child is above or below the average weight shown.
Height
To measure baby's height, lay him or her with back flat and head positioned against a wall or other flat surface. Gently stretch both legs straight and measure form wall to baby's heels. (This is easiest to do when one person holds baby and another holds the tape measure.)
Chest
Measure a loop under your child's armpits, passing the tape across fullest part of chest and around shoulder blades.
