This is my first post so sorry if I dont make much sense... my 12 week old has always been a good sleeper from about 8 weeks she would sleep 830pm-630am waking occasional, but would go straight back of once popping dummy back in. We start her night time routine at 7, bath, pjs and bottle. She then settles herself of to sleep by about 830pm .But the last 5 nights she wakes at 12pm and is up every 30/60 mins wriggling and grunting till the morning. She ends up wriggling to the top of the cot and banging her headsometimes I can put dummy back in and she goes back for another hour sometimes I have to put the dummy back in for what feels like a 100times before she goes back off. Ive tried feeding her when she wakes repeatedly around 3/4pm but she only drinks a couple ounces and then falls alseep while drinking. As I have a 5 year old I have to get up and do the school run every morning and am getting very tired from the lack of sleep. Any ideas???
