I put my small, annoying child in the oven
Why do you plan on putting her in the oven?
She was being annoying so it was the perfect spot for a time out.
Children can be annoying but you cannot put them in the oven. It is wrong and could kill it. It would be better to raise the child so it won't be as annoying.
She said something in public that was embarrassing, how do you expect me to raise a child in a public place? I'm right on this one.
Hurting a child for saying something bad is really dramatic. If you feel you are unable to care for the child you should ask if a family member can take them for a while. Not everyone is fit to be a parent and that is ok.
