These AlbertoCubatas Baby Nap hoodies are really easy to use. Just put them on and enjoy the comfort. When it comes to washing, make sure to turn them inside out and wash them in cold water with similar - colored clothes. Only use non - chlorine bleach if you really need to. After washing, it's best to hang them to dry, but if you're in a hurry, you can tumble dry on cool or low heat. Don't use fabric softener because it can make the colors fade. And remember, don't iron or dry clean these hoodies to keep them in good condition. They come in sizes from S to 4XL, so you can choose the one that fits you best.
