Using this baby onesie is super easy. Just unfasten the bottom poppers, slip your baby into it, and then fasten the poppers back up. It's perfect for everyday wear. When it comes to washing, remember to turn it inside out and use cold water in the machine. This helps keep the fabric soft and the colors bright. Set your dryer to a low setting to avoid any damage to the onesie. Always check the onesie for any loose threads or small parts before putting it on your baby to ensure their safety. Enjoy dressing your little one in this cute and comfortable onesie!
