I am gluten and dairy free and didn't have a problem on VG. I was able to find almond milk (I can't remember if it was at Rosie's or Bucks - sorry). We typically end up buying groceries at both Rosie's and Bucks in order to get everything we need. Buck's had some great cut up fruit salads in their prepared food section and I ate these every day. Most of the restaurants on the island offer salads and one or two grilled meats. If you want a splurge, visit Little Dix Bay - wonderful Gluten Free bread in addition to fantastic food. We are heading down in July and I will bring some rice cakes in my bag so that I can have a snack anywhere. Have fun & don't worry - you will be able to find plenty for your daughter to eat.
