DS3 still had two sleeps but on Sundays only gets one. We are at church and he doesn't sleep there so he goes down when we get home. This means that I generally plan to be home on Mondays so he can have his normal sleeps. He will sleep for 1.5-2hrs in the morning and 1-2 hrs in the afternoon. This is how I tend to operate now. If I know I'll have a day where he's only going to get one sleep I plan the next day as a home day to make up for it.
