I loved Bali. I would go back in a heartbeat
As long as your ds doesn't drink the tap water I think he will love it. So many family orientated activities I.e waterbomb park, wildlife parks
We stayed at kuta beach lagoon. Was in the perfect spot if your main goal is to do some shopping
There are loads of western run and owned restaurants that will understand so you will survive
Enjoy yourself Bali is the best
