I can't remember quite what it was like for my first, but my 1 week old simply won't sleep when I'm not holding him (well, we got a bit under an hour last night, big success, but that was it for the whole time, otherwise he was feeding or snoozing on the boob so I was awake all night).
Keep trying to remind myself just how very little he is, and that it's really early days. But I'm spinning out rather.
Anyone coming out of the other side of something similar?
