To use this sweatshirt, simply put it on your baby during nap time. It's super comfortable thanks to the removable tag. When it's time to clean, just throw it in the washing machine on a cold cycle. Make sure to turn it inside out and wash it with similar colors. Only use non - chlorine bleach if it really needs it. After washing, you can either hang it to dry for the best look or use the cool/low heat setting in the dryer. Don't use fabric softener because it might make the colors fade. And remember, no ironing or dry cleaning. This way, your baby's 'Baby Nap' sweatshirt will stay in great shape for a long time.
