Can you post for me, please? My son's Make-a-Wish trip is a Disney Cruise. He REALLY wants to go on an excursion to a place that has a ton of crazy water slides. (He loves them!) He has a g-tube, how would you keep it secured on crazy water rides? I was going to grab a drug store abdominal binder but I didn't know if you awesome moms had any proven suggestions. He's 46 lbs and 45". Thanks in advance!
