I love having the youngest do a morning nap/rest even if it is half an hour because then I can concentrate on crafts or whatever with the older ones. One of the reasons our outside playtime is after afternoon nap is because I don't mind taking little ones so rarely have months without someone napping in the morning.

Depends a lot on your area too in the sense that some of my kids are up at 6 and to daycare before 7 so by 9 am they have been up over 3 hours and starting to get cranky. It just makes for a better day for all of us if they get a short nap.
