My DD has generally been a pretty good sleeper only up once or twice a night so this has thrown me. Last couple of weeks she has gone from sleeping well in her own cot in her room to absolute hysterics the moment I lie her down. Our routine is lights down, feed to sleep & transfer to cot. The last 2 weeks I've successfully got her to sleep as normal but she wakes the second her head hits the mattress.
Last few nights I've persisted, picking her up, resettling her and putting her back down over and over but it's not working, last night I was up until 4am and she didn't sleep for a single minute in the cot, by 4am she was crying so much I thought she'd be sick, so she ended up in our bed. It's like she's a newborn wanting only to sleep on me (except strangely she wasn't actually like this as a newborn).
I'm not dead against co sleeping but I was hoping not to do it long term and me and dh were enjoying having our space and evenings back, is there anything else I can do?
