Uh-oh... I'd put him back in the crib! Moving to a new house is a big enough change without adding the stress of a new "big boy bed". We made a similar mistake with my stepdaughter, but once we gave her old bed back, and let her have time to adjust to the new house, she was ready for the sleeping arrangement change. It took about 5 months for her to be ready, and even then, we really played up how special and exciting it was gonna be to sleep in her own "big girl bed"! We talked about it for weeks before actually changing the beds around to let her get used to the idea and even left the old one in there for a few days in case she wanted it. You couldn't walk in her room, it was so packed! LOL Good luck!
