S.A.
I would totally do the pack n play in your room until he's over this phase. Clearly, nothing else is going to work and who wants to be cleaning puke sheets 3x a night?!? Plus, it will help to get him used to the pack n play for when you're on vacation. My 21 month old son is starting to go through this too for the first time. I didn't think he would at all because he was the only one of my babies that would let anyone hold him, and wasn't afraid of strangers. Now that he's almost two, he's starting this. Weird... Good luck!
