• Sleepsuits should always have a snug fit on your little one for safety.
• To measure your baby lay them down & lay a measuring tape from the top of their head to the bottom of their heel.
• For older little ones you can measure them standing up.
• If your baby is nearly the size up, we always recommend going for that size to make sure the product lasts longer.
