Dd id 6 weeks old and will only sleep while being held. If I put her down, even if she is fast asleep, she will be awake and crying within minutes. Propping the basket up doesn't help, and she'll happily sleep fully horizontal on me or DH so I don't think it's silent reflux. She's fine in her pram - as long as it's moving.
The only way I've been able to get any sleep myself is to co-sleep nursing her, but it still takes about 4 hours of lying-down nursing before she drops off (usually around 2am when she's worn herself out with her fussing), and she wakes frequently to feed/fuss and takes an hour or more to get back to sleep each time.
Last night I was so desperate for sleep that I nursed her in cradle hold rather than lying flat, and I just slept on my back, propped up on pillows while she did it. Amazingly, she slept from 11.30pm until 4.30am, and I got nearly the same amount! After changing her and nursing her again she was spark out so I tried a variation of the 'Ross and Rachel bed roll' so she was safely lying on the bed rather than on me. That lasted all of five minutes, and after a couple of hours of trying to settle I gave up and slept with her in cradle hold again. We both then managed another couple of hours' sleep. This was the most I've had since she was born.
I know it's not safe to sleep while she's sleeping on me, but have no clue how to help her to sleep off me. Any advice please?
