We can go out at night & not get DS to be til very late & he will still wake around the same time every morning. The only time he sleeps in, like today is if he refuses an afternoon nap.
I found he was waking at 5am, but would cry not be all happy and chatty like after a day sleep....so I go in with the lights still off & give him a feed & put him back to bed & he will sleep til usually 7.30, that works well for us. I like that he's in bed by 7pm most nights as DH & I get time together to chat, eat tea etc.

Just a msg for Fiona, what time does DH start night shift? My DH also does night shift & I found it earsier when DH was cooking a meal for his tea that night to sit & have a plate early whilst he was still there. That way I had something to eat & I could free myself up from cooking etc to relax when bubs was alseep. Though his night shift didn't start til 5pm.
