As the title says really, my 7 week old DD writhes and kicks her legs, while grunting, for hours on end while asleep. She sleeps really well, for several weeks now she’s slept from approx 10pm-5/6am without waking for feeds but from around 2/3am she is loudly grunting and kicking her legs out, bringing them up to her tummy and general looking and sounding very uncomfortable. But every time I check, she’s still completely asleep, plus when she does wake she doesn’t have a dirty nappy, and isn’t desperate for food (just hungry as normal) so I don’t think it’s discomfort from anything like that. I’m assuming it’s not painful for her as otherwise it would presumably wake her up, but is it fine? Can I do anything to ease it? Not only does she seem uncomfortable, but it keeps me up as well. I’m a terrible sleeper and even though she sleeps through the night, I’m up from 3ish because of her noises (I know generally I am very lucky with the amount she sleeps!)
