What is the worst example of pushy parenting you have witnessed?

This question was inspired by WillWorkForChocolate’s recent question about allowing her daughters to skip their gymnastics class every once in a while and how some people think she is wrong for doing so.

I have worked in sporting environments for some years now and see lots of children of varying talents (some incredible, some not so much) play/train here. I often have to deal with parents who believe their children are more talented than they are and feel they should be in a “higher ability group” than the one they are currently in. Having to break it to the parents that their child is not as gifted as they believe is difficult but, for the child’s sake, we have to do it, politely, of course.

There are some parents that will push their children to do well, sometimes at the expense of the child’s health and happiness.

What is the most extreme example of pushy parenting you have witnessed? It doesn’t have to be in the sporting world.

Before anyone asks, I have seen Toddlers and Tiaras and it makes me cringe. However, I am after more personal accounts.
