Please do.......maybe you should consider doing what we ended up doing by putting her in a tee shirt and shorts and still applying sunscreen on her face, ears, neck and legs everytime she gets done playing in the water. Take Aleve and Benedryl just in case she does get burned and start giving it to her immediately.
Another tip.....wear some kind of flip flops, etc when you are going to the beach. The sand gets extremely hot until you get down to where the waves wash up on it. Please heed this advice. Like I said earlier, DH got an actual blister on the bottom of his foot.
Enjoy yourself and be careful.
If you got any other questions.....let me know.
