aww, im sorry hun. the sleeping arrangements i'm sure are not making it any easier on you.
my daughter would get used to getting up, after a bad week with teething, or her being ill. she would just get in the habit and continue to wake up after those things had passed. once i checked on her and knew she was 100% ok, i would just have to make myself let her go.
most times she never cried for more that 10 or 15 minutes and she would go back to sleep. other times she would lay awake for up to 2 hours, sometimes not even crying but just rolling around and being awake. i could hear her on the monitor but i wouldnt go to her, only b/c i didnt want to keep up the habit you know. either way, even if she wasnt crying, i was still awake when she was... it's just a mom thing :o)
its hard to say if she is in your room, she might just be able to get up and look right at you. can you use a room divider or something to partition it off a little and give her and you some privacy? it might be a good idea since she will be moving into her own room, to help her get used to the idea of being away from you (baby steps.)
i feel for you with these sleepless nights. i hope you find something that works for your situation. please let us know how it turns out. and good luck with your new construction.
