Mine knows the jig is up (she's 2.5). Her sleep took a major backwards turn (from putting herself to sleep and sleeping 12 hrs solid to fighting sleep, having to be cuddled to sleep and gettin up 3 or 4 times in the night) and she stopped cooperating in most everything. I was pretty much a basket case in September. Now that we are almost there things have improved a lot...we've been reinforcing with her how we will love her just as much when the baby comes, reading a lot of books about being a big sister and new babies. I feel for her, this 'baby' thing is so abstract to a 2 year old, it may just suck for a while, I'm afraid, but I hope that the baby physically being here will help her make the conection better.
