Part of the reason I think is that I've been sleeping later. Normally, I would get up at 9:30 or so and DS would hear me and get up. I've started working late evenings and sleeping till 10:30 or 11. DF has always been a night owl and would sleep till 2 if I let him. In the past, DS would knock at my door when he woke and I'd get up. Now I think he just goes back to sleep till he hears me get up.
How can I get DS on a more normal sleep schedule without making him insanely cranky for a week?
