All my kids have been in my room/bed for months. DD3 (18 months) & DS (4) both sleep in my bed now. DS not every night, but 90% of the time. (It is different now I'm single.)

DD1 wasn't in our bed much, but the other 3 have been from very early on. With the babies right next to me, they rarely cried long enough, or loud enough to wake ex. If they did it was a really bad night & they were usually alot older. I would leave the ensuite light on, or I had a lamp for night feeds/changes.

I would give your H the option of the couch or the bed. Or get an extra single bed somewhere for him if its needed. There are sometimes circumstances, but I really don't think its fair that only one parent has to adjust to a new baby while the other continues to sleep 8 - 10 hours straight a night.

Sleep is a must for workers, especially in some industries... but us mothers can't drive a car with our children in them safely if we are sleep deprived... That is not safe.

I'd see how it goes for a few weeks, then think about weather or not changes need to be made
