DD (15 weeks) was sleeping 7-10 and 10.45-7 although odd wakings in the night due to growth spurt at 8 weeks, coming out of swaddle, dirty nappy etc.
The last 2 nights she has woken at 2am and 3.30am respectively just crying quietly (not like she usually does when she wakes) so I go in and offer her a feed which she will take half heartedly for 40 mins. Rather than falling asleep on me like she usually does with night feeds she stops wanting to feed and starts crying and arching her back. We tried rocking, walking, leaving her in her cot but she just cries and when we pick her up claws at me and DH.
After 2 hours the first night, and 1 hour last night we resorted to calpol and she fell asleep 10 minutes after having it and we've woken her both mornings at 8am and she is not really hungry.
I don't think its a growth spurt but I've no idea what's causing it.
Any ideas?
