I was using the bathroom today and as soon as the door closed my baby started to cry. I hear stories like this a lot and often the children are banging down the door or worse. I think we like to tell these stories to sort of one-up each other. "My children are such monsters!" followed by "Mine are literally vampires!"
I like my children a lot. Sometimes I'm frustrated by things they do. Most often I am frustrated by things that apparently I have not been successful at teaching them not to do.
As a parent, it's nice to know that other folks struggle with similar issues. And I think it's ok to teach your children to behave, if you can.
