Hi C.,
My son was just about the same age when we moved. The biggest piece of advice that I can give is to talk to her about what is going to happen, step by step, in the days before the move. It'll help her know what to expect, which I find toddlers really seem to need. She may not necessarily understand it all, but it may help.
Also, do a little research into the resources near your new home. I found a "mommy-and-me" class that helped us adjust and get our bearings right after we moved. Is there be a park nearby? Sometimes there will be friendly dogs out with their humans. Do you have friends nearby who can help "substitute" for the old neighbors until you meet your new ones?
Hopefully she'll just go with the flow - sometimes they surprise you. Good luck!
