I currently go to a non-denominational church, and they offer seperate rooms for each grade and age group. It is fantastic, and I cannot praise it enough.
The WTS just wants to be different at all costs, and it is stupid, and are only hurting themselves.
I have a toddler, and I cannot imagine trying to sit through the meeting for two hours, trying to keep him from running everywhere. There just is no possible way at all.
