I have a 23 week old DD, diagnosed with CMPA at 8 weeks and slept through the night since. Until just before xmas and now she's waking up constantly through the night, she's not hungry, uncomfortable, too hot etc. She just wakes up and will either just want her dummy or she will lay in her cot wide awake babbling, which turns to frustration and then you turns to crying. My DP is away during the week so I'm doing it on my own and due to return to work next month- I'm SO tired. How am I going to cope?! When does this so called 'sleep regression' end?!?! She's a joy and such a happy baby and I try not to take any of her for granted but when it's 4.30, the 8th time I've been up with her and I've been sat at the side of the cot for 45 minutes trying to get her to sleep it's hard to think of anything else other than sleep!!
