I agree, that word always had a bad sting to it when my girls used it.

i was not allowed to use that growing up

hmm. Make her write sentences whenever she uses it?

I thought about that. I wasn't allowed to say it growing up either. Not sure how to ban it.

Mine went through that phase till one day I told her I hated her too. She looked at me and laughed. We both started laughing and saying..

it as a joke. She stopped saying it for real.
