Using this baby onesie is super easy. Just slip it on your little one through the top and fasten the poppers at the bottom. It's great for everyday wear or special occasions. When it comes to maintenance, remember to always turn it inside out before putting it in the washing machine. Use cold water to protect the fabric and colors. After washing, you can tumble dry it on a low setting. Be careful not to use hot water or high - heat drying as it might shrink the onesie or damage the fabric. And always check for any loose threads or poppers before dressing your baby to ensure their safety.
