I think it's generally recommended that you keep baby close to you to begin with at least - the closer they are to you the safer (from a SIDs perspective). I think it would be really hard to be separated from a newborn too - couldn't imagine doing it myself.

They can be noisy breathers and make all sorts of noises during the night, in addition to crying when they wake up. But, you'd be surprised what you partner can sleep through. In any case, baby comes first, so if he's not getting up to help and doesn't want to be woken up then he should find somewhere else to sleep.

And, the closer they are to you the easier the night wakeups are. Having them in bed with you = least possible disruption. It's not for everyone, but something to consider. You can keep nappy supplies by the bed and just do it there. You only need to change them if they're poohy (unless soaked through obviously), and may find it's not too long at all before you can leave them all or most of the night without changing.

Many little babies prefer smaller spaces to sleep at first, to mimic their containment in the womb, so you may find a bassinet or something like that works better.

Above all - you will find through trial and error exactly what works for you and your baby. You can't really know for sure till you're actually doing it. All the best~~
