Many of the upscale hotels/resorts have access to very reputable babysitters. That should not be a problem at all. I have a dear friend that hired a sitter for a night out on the town and was very happy with her. The rates are reasonable as well. If you DO take your kids, be sure to stay at a place that can accomodate them. I suggest a first floor unit, and one with a kitchenette so you can make snacks, refridgerate milk, cook a meal if they don't like the local food etc. There is a playground near the center of town. Is there any way that you could bring your own nanny? That way you could all enjoy the reef, and not worry about the baby. I know Caribe Island Resort has pool toys for kids, a water trampoline, and a little restaurant with food kids would enjoy. The kitchens in the rooms are wonderful, and I know the folks that run it. They will bend over backwards to help you. Check their website. If you can stay longer by bringing the kids. Bring them. There are doctors on the island as well. I brought my kids a couple years ago, and they were able to treat an ear infection. It gave me peace of mind. Debbie
