hello in a few months we will be going on a long car trip about 18 hrs total will be broken up into about two days of driving and i was wondering if I could get some advice on my 11-year-old is it ok to keep him in diapers or pull ups in the car during the trip he has a night time wetting issue so maybe just for the car ride he has not had any accidents in the past during the day but he's not real good on telling us things like when he has to go potty would that somehow scar him or something I'm thinking of just diapering the whole family but i just need help with this issue he dont mind wearing at night but has anyone else done this for long trips ?????
