To use this swimsuit, simply help your child put it on like any other swimsuit. Make sure it fits well and is comfortable. When your child is done swimming, rinse the swimsuit with fresh water to remove any salt, sand, or chlorine. Hang it to dry in a shaded area to prevent the colors from fading. Avoid using harsh detergents as they can damage the fabric. Store it in a cool, dry place when not in use. Also, check the swimsuit regularly for any signs of wear and tear. If your child has sensitive skin, you can apply a little baby lotion before putting on the swimsuit for extra comfort.
