Let me clarify.
She did not melt down because we were leaving. She was fine when we left. She melted down when she took another child's bike, and I asked her to get off the bike because we were leaving, and we also did not know the child who owned the bike, and we did not ask their permission first. She was fine until we were almost to the car, when she suddenly threw herself on the ground and it all started from there...delayed reaction, perhaps?
She was not "punished for a week." The only thing that has been taken away are her playgroup outings (1 so far, and AFAIK there are none scheduled for a while) for one week. Other than that, she has not had any other restrictions. She has been to the park, plays outside, has all of her toys, even got a treat at the store yesterday. She has not been locked in her room for a week, or anything like that.
I would like to ask that if people want to disagree, that they could at least offer some advice, because I'm feeling a lot of criticism, but not a whole lotta help. There have been some great ideas, but I'm also feeling like some people are quick to point fingers without offering any real solutions, which really doesn't help anything. So please, if you just want to point out what a crappy mom you think I am, keep it to yourself. Thanks.
I think that people are debating about the appropriate way too handle this, not trying to make you feel bad. I don't think anyone thinks that you are a crappy mom, and I don;t think that anyone meant to imply that (myself included)
