Sunday during church, the mother in front of us let 2 of her 3 daughters (around 5 & 7 years of age) completely misbehave. At one point the older of the two, was hitting the younger one in the head with a shoe, as well as stepping on her head. They were out of control.
There are rules when we go to church. Our children are not allowed to sit next to each other. They generally keep themselves occupied with all the bible puzzles they hand out when you come in. Occasionally we will have to tell them to be quiet or to stand up and sing, but generally they are good.
The difference is, I will carry my child out when they are misbehaving. Even to my utter embarrassment.
