Last month we transitioned DS1 over to a twin bed from his crib and he made the transition pretty well and generally does great going to bed. We just got back from vacation and it was an awful bed time experience. We had one bedroom for the four of us (my DH, I, DS1 and DS2). We brought a mat and a sleeping bag for him for the floor and a pack-n-play for DS2. DS1 would not go to sleep! He kept getting up and wandering out and anytime we would try and lay him back down he would scream and cry and of course wake up the baby. It took three hours just to get him to fall asleep all four nights we were there! It was horrible. Anyway, we have a few more trips coming up this summer and I am about ready to cancel them. Any recommendations for something that worked for your child?
