That is a lot of change for a little guy but remember they are resilient. We went through a few big changes when my daughter was 23 months old (new baby, new house) and at times I felt she was stressed. I tried my best to keep her from seeing ME get stressed because kids often pick up on our emotions. My advice - lots of reassurance ('talk up' the things you think he'll be leary of), one on one time w/ mom and/or dad every day, and just take it one day at a time. Good luck! Sounds like the next few months will be busy for your family but it also sounds like you've got everything under control. It will be fine!
