I've gone through the Gabb watch and now a phone with my oldest kid,and we have loved it so far. I'm starting to look at the watch now for my youngest. My problem is she has limb differences and has very small wrists, 5 inches to be exact. I'm trying to find the smallest size of the watchband + watch, as going much over the 5 inches as it means the watch will fall off as she doesn't have the width of fingers to help hold it on. It's been awhile since we had a watch so I'm not sure how small it can go. I'm fine buying the sports band if needed, I just need sizes and I can't find anything.
