Using this baby onesie is a breeze. Just slip it over your baby's head and fasten the poppers at the bottom. It's designed to be easy to put on and take off. When it comes to washing, remember to turn it inside out and use cold water in the machine. This helps protect the fabric and the design. Tumble dry on low to avoid any shrinkage or damage. Also, make sure to check the onesie regularly for any signs of wear and tear, and keep small objects away from it to prevent choking hazards. Enjoy dressing your little one in this cute and comfortable onesie!
