I'm a teacher going back to work on Wednesday after 4 months of maternity leave, a week and a half of end-of-term fun and then the six weeks holiday - six months in all. I'm not worried about leaving my daughter - we have found an amazing childminder - but I'm quite concerned that the lack of sleep will render me useless. She's in the throes of a sleep regression and I'm exhausted! Annoyingly, two weeks ago she was sleeping fine, it's just now that I actually need to function that she's waking up so often. A bit of hand-holding would be very much appreciated.
