I think I have been pretty lucky so far (knock on wood). Today the babies went down at 9:00 yesterday it was 9:15. Today they slept for 1 1/2hrs. I just got all the kids including the babies to sleep at 12:30. I'm hoping it continues to stay like this. My age group is (2)5 months, 23 month part time, 3 yr and a 3 1/2 which is part time until 7pm (I will probably be terminating this week for on going behavioural issues)I will be starting a 1 yr old next week who's mom has been working within my schedule. She is part time and will be filling the 23 months days.
