My DH works shift work, day shift is from 6.30am to 6.30pm & the opposite for night shift & 7days a week. So our DS is in his own nursery, this works best for us as he is not woken early by DH when he gets ready to head to work & he doesn't wake him when he gets home from night shift.
Though usually after a night shift DH likes to wind down with a drink & a bit of toast.....so we are up before he heads to bed & he just pops the earplugs in & we try to head out for the morning.
It gets easier as they get older, as DS now often sleeps through & wakes up chatting to himself...so I lie in bed talking myself into getting up LOL til he is ready to get out. Or he has a 4-5am feed & sleeps til 8am.
But shift work is a pain & yes I used to bring DS into bed with me for & watch sunrise if he was up too early , but if DH was there sleeping I just hop out of bed a deal with it that day. I also do all the night wake ups unless there are several & I need a hand or DH is on his days off.
With that roster we need as much time together as possible, so I find we need our bed & having DS in his own room is the best thing for us.
