i can remember things going haywire around that time, i think hang in there and in a couple of weeks things will settle down..... my dd has been the most shocking sleeper, and touch wood, i can now say, at 11 months, it is EXTREMELY rare for her to wake and need me overnight.... i don't know myself.
it will eventually happen just hang in there you're not doing anything wrong, she's just a lil bubba who is realising she is out in the big wide world...
