A couple of things to add to your first aid kit--bandaids, polysporin, cortisone, and Imodium. All of these are readily available on the island, but doesn't hurt to have some on hand. Especially with kids, the food is different than what they are used to, and may give some a bit of a problem. Blisters are common, or stubbed toes, and maybe a bug bite or two. I know some of the resorts will call a doctor to come to your resort for you. Not to worry! The kids will have a ball.
