What the hell is the difference it could be church, it could be your home! there are times you can lose track of your kid *I DONT CARE WHERE* and it can kill them... If it does just hope some A'Holes on a website do start crowing how you had it coming and preening about what perfect parents they are!
You are being totally irrational and making false claims because I think that even you are realizing that you are losing the argument.
If anything can happen at any time, that is all the more reason that you keep the kids under close supervision. especially at that age and especially in an enviroment where the conditions are less than ideal for watching them.
