I have a 13 month old and she was sleeping from 9-10:30 in the morning and 1-3:30 in the afternoon then abruptly she stopped sleeping in the afternoon and just screamed instead so what I did was I changed her morning nap. I now put her down at 8 and I wake her at 9 which is just enough to get get through lunch and shes still tired for the afternoon nap. Now her afternoon nap starts at 12:30. This works perfectly for my schedule as I have two that go down at 12 and the rest go at 12:30. My pick ups start at 3. I have one that leaves at 3 one at 3:15 one at 3:40 one at 4 and the last one at 4:15. My break is from 12:30 - 2:30
