Put him on a blanket and scoot him into the back of my van. Back seats fold flat. Middle seats flip forward. He'll fit! LOL My friend's son Sam sleeps (or seems to be sleeping) whenever he is overloaded with sensory stuff. Love to you both. And remember, if you need anything that I am capable of doing, let me know! We're thrilled Sam is going. Sad you both will be away. But happy, too.
