DD is 20 weeks, had previously been going to sleep happily in a bedside crib at 7.30 and first waking at about 2 or 3 for a feed (comes into bed with us) then maybe again every couple of hours until 7 up for the day. I could feed her to sleep lying down and we both had a reasonable night.
Last couple of weeks she's been waking up when we go to bed (about 11 or 11.30) and won't go back to sleep on her own, so I've been feeding her. She'll nod off lying down on the boob after about 5 minutes vigorous sucking but if I try to take the nipple out of her mouth (to get myself into a more comfy position or because it gets sore after an hour or so ) she wakes up and gets cross (had been trying the NCSS pull-off thing but she's too sensitive to it now). Then she won't go back on again to finish off the feed, sometimes she decides that it's time to get up for the day and wants to be played with and refuses to sleep (so one of us takes her downstairs til she gives off tired signals again), other times she'll sort of go back on the boob but kicks and pinches and scratches a lot. The average pattern for the last few nights has been sleep 7.30 til 11.30, awake off and on from then until about 4ish, either I or dh gets up and puts her in the sling or just takes her out of the bedroom, and then she might sleep another hour or two if we're lucky.
This means that come the morning I have no idea how much quality sleep she's had, or when she last fed for the purposes of knowing if she's actually hungry. If I sit up with her for the feeds instead of lying down she wakes up when I try to put her down again.
I've had about 4 hours sleep max a night for the last week it seems that she's similar, only gets a good stretch in before midnight. Her first tooth appeared on Monday and she's had a bit of a cough but we can't work out how that's affecting her sleep so badly. Is there anything we can do to help her get back on track? I'm sure this will pass eventually but meanwhile she's often very angry in the daytime and won't nap unless I feed her to sleep then sit very still...
