Size Guide

Please refer to the following table when selecting size. Remember safety first when choosing sleepwear products and select the child’s true size. While growing room in every other style is always an advantage, it is especially important that sleepwear is worn snug thereby reducing the possibility of catching fire.

A child’s height is the best way to choose a size, because all kids grow at their own pace. Measure the child’s height from the top of the head to the floor. You should also consider their weight if a child is above or below average. If you are buying a gift, and do not have the child’s measurements, refer to the age guide and if in doubt order the next size up so they can grow into it or our e-gift certificate might be a great option.
