Using this baby onesie is super easy. Just slip it over your baby's head and fasten the poppers at the bottom. The short sleeves and stylish design make it very comfortable for your little one. When it comes to maintenance, remember to machine wash it inside out in cold water. This helps keep the fabric soft and the colors bright. Then, tumble dry it on low. Avoid using hot water or high - heat drying as it might shrink the onesie. Also, always check the onesie for any loose threads or damage before dressing your baby in it to ensure their safety.
