My 4 month old dd sleeps with us mostly as I have never been able to get her to settle for much more than an hour without being held.
She squirms loads, especially at night. Often ending up with a forced out trump. Not sure if that's a cause or a product of the squirming though!
It's almost manic squirming, she cries out, it wakes her up, her arms flail all over. We have worked out that if you can manage to get a dummy in her mouth (not easy as she shakes her head about a lot too) and stand up and rock her, then she MIGHT stop and sleep. Not always though. And not ideal with an easily disturbed 3 year old sleeping in next room.
I know with a baby you shouldn't expect sleep. That's fine.
I get cramp in my arm from having to hold her all night. I also think that she is often very tired. I feel like she needs more peaceful sleep. Some days she can have naps of no longer than half an hour at a time. She wakes up tired.
We have tried swaddling. Sometimes she settles for longer on her tummy, which I don't mind doing in the day when I can keep checking her, but dont fancy at night.
I would love any ideas on why she is squirming. Also how do other people get their babies to just sleep in a cot? Neither of mine have, what am I doing wrong?
