Using this baby onesie is a breeze. Just slip it on your little one through the top and fasten the poppers at the bottom. It's designed to be easy to put on and take off. When it comes to maintenance, remember to always machine wash it inside out in cold water. This helps keep the colors vibrant and the fabric in good condition. Tumble dry on low to prevent any shrinkage or damage to the onesie. Also, keep in mind that the cotton is very soft, so it's gentle on your baby's sensitive skin. But avoid using harsh detergents as they might irritate your baby's skin.
