Hi, my 7.5mo DD has suddenly decided that sleep is for wimps. She used to nap pretty well during the day (no long sleeps but would go down within 10 mins and sleep for 45 mins, spending 2 and a half hours awake at a time). A couple of weeks ago she wasn't seeming tired at nap time so I extended the time awake up to 3 hours. This worked for a couple of days, and since then she has got worse and worse. She won't go down to sleep - e.g. spent 1.5hrs going down for morning nap today! Went back to 2.5hrs awake in case she was just overtired for a couple of days but made it even worse. She seems perfectly happy for a lot of the time that she is meant to be going to sleep - rolls over and practises crawling on her front (she's in a grow bag but still always ends up on front) but just won't sleep. Evenings have got worse too. She slept through the night for the first time at NY, 2 nights in a row, so we got really overexcited and then things went horribly wrong. She now won't settle easily at bedtime (we have a good routine), then wakes usually at around 10.30 and cries for a good hour, despite working hard to calm her. She then wakes again in the early hours, and after spending ages trying to calm her we've started to give up and take her into bed with us (sometmes works, sometimes doesn't). I don' think it's teeth as she hasn't been like this when her previous teeth have come through (it's been more of a short, sharp, scream-all-night-for-2-days-then-tooth-arrives-and-fine). I'm exhausted and going back to work in less than a month so need to sort it - compounded by problem that I'm currently the only person who can (eventually) get her to sleep - even her dad struggles - and we need nursery and grandparents to be able to do it soon. Aaaaargh. Help please.
