My son is 3 years old and has Autism. He is not severly affected (we are blessed in that way), but he has his sensory issues. He doesn't love the airplane, but we manage it with distractions and snacks. We have been to WDW with him 3 times. I was wondering if any parents with Autistic children have been on a Disney cruise. Any tips? He only drinks Very Vanilla Silk brand soy milk, and I am very worried about him getting this onboard, as well as the VERY limited about of other foods that he will eat. Unfortuantely with all of the travel regulations it gets difficult to travel with fluids. I have seen the juice box style of silk boxes at Walmart, and we have used those for short trips. I could potentially put them in a suitcase, or even have a box shipped (maybe we will do a WDW for a few days first- trip). Any cruising ideas for us? We also have an 8 year old daughter and another 3 year old son (a twin). Thanks for your help!!!
