What we did with child number 2 was we switched rooms, gave our son the master bedroom and put and bassenet in our room but put the crib up in his room , at his request, that made him really feel like the big brother, he had already been out of the crib and on his crib matress on te floor to get him used to no bars and then at 2 put him in a twin bed, make it an adventure, like a camp out, just get real creative, the key to change for children is to put so much positive in the front of things so they only see the fun and the adventure, in this situation is get him in there has soon before the baby comes as you can, at 2 this is a big change, so be patient, and maybe he can camp out on mommy and daddy's floor for a couple nights, build up the big boy idea, and he should do just fine. Congradulations on your new baby coming. J. L.
