As you know DD is a shocking sleeper. But we have recently had two night where she has slept through till about 0530 for like the first time ever! So there is hope. Dd is also fed to sleep if she wakes overnight but being pregnant it is hard with the sensitivity. So when she wakes and won't got to sleep without boob I say cuddles with mummy or in the cot (kind of mean I know but I was desperate) an if she still cries being in my arms I place her in the cot (we have two and this one is near our bed) for like a few seconds no more (like sometimes I don't even let go of her) and pick her up again and say cuddles with mummy or in the cot and if she is crying I repeat the process. But usually she will put her head on my shoulder and let me cuddle he so I can lay down and it has made a huge difference to her when she wasn't responding to anything else. Some nights it won't work and I will feed her because figure something more is wrong. Or at times I will get her up and offer her water...haha cos i don't know what else to do.
