This baby set is super easy to use. Just put the bodysuit on your little one first, then slip on the pants. The headband can be gently placed on their head. When it comes to maintenance, always follow the care instructions - machine wash in cold water and tumble dry on low to keep the colors and fabric in good condition. Be careful not to use bleach or harsh detergents as they may damage the fabric. Also, check the size chart before purchasing to ensure a perfect fit for your baby.
