Newborn won't sleep unless being held.

[PollyBlue6]

He's 3 weeks old and won't sleep unless being held.

We've got a next 2 me cot, as soon as he knows one of us isn't holding him he starts crying and we are up and down like a yoyo with him all night.
We've got Ewen the sheep which works to an extent.

Not only are we exhausted but he is too, he's overtired which means he's grumpy most of the day, usually the afternoon.

I'm worrying about safe sleeping and SIDS.
Has anyone just cuddled/held their newborn most of the night?
All the guidelines recommended the grobag, next 2 me cot and blah blah blah which wr have got but he doesn't like any of it.

This was me - I was so desperate at the time. But it did pass. It took a little longer than for some babies but it did get better. I remember the first day DS slept in his cot - itvwas only 20 minutes but we thought there was something wrong with him! A sling helped and co-sleeping helped - look up how to do it safely. It was still totally crap for about 3 months though. There is no such thing as "sleep when the baby sleeps" if they only sleep on you! Now (9mo) he sleeps in his own room and rarely wakes up in the night. Phew!
