Using this baby sun hat is super easy. Just place it gently on your baby's head and adjust the Velcro until it fits comfortably. When your baby is out in the sun, this hat will protect their delicate skin from harmful UV rays. Remember to check the fit regularly, especially as your baby grows. For maintenance, hand - wash the hat in cold water with mild detergent. Let it air dry to keep the shape and the color of the cute cartoon design intact. Avoid using harsh chemicals or machine - drying, as this may damage the cotton material.
