I'm not going to take pictures of my daughter in dance class. I'm also going to keep her mother from watching.
What is going on between you and her mother?
She's always telling me that my daughter is not good.
Talk to the mother about this. It is not good she is saying that about your daughter.
I have no clue why she can't enjoy it. She is just petty and I don't care.
You should care for the sake of your daughter. This conversation between you and the mother needs to happen now. Two parents need to be on the same page to raise their children.
