The best "kids included" meetings I was ever at, had a room off the main meeting room and different people would take about 10 minutes each to mind the kids. There were books and toys and a changing table, and the kids were happy.
I agree that it is important to get to a meeting, with the kids if a babysitter can't be found, but I also feel that many of the stories are not appropriate for their age, and also if there is a speaker then that time should be quiet so the newcomer can hear.
God bless the child!
