I am going through this too. With the new school year I took in 2 babies 15 months and 18months, i have a total of 5 but only 3 nap. I had no choice but to take them at the same time as both parents were going back at the same time. So baby 1 will scream and cry for over an hour and he is now getting out of the play pen and coming down stairs how on earth can one so small do this? and baby 2 is the same minus the getting out of the play pen. i have tried everything its been 6 days now and i am getting tired. the other napper is great he is sleeping fine for now with all the screaming. mom and dad are no help as they sleep with them at home?
