My friend has a very rough toddler who pushes, hits and bites. She is lovely but she doesn't do anything to stop him from hurting other children and simply says she can't control him. Her child recently pushed another child off a swing and broke his arm. I thought it might be a wake up call for her, but it wasn't. Do you have any advice about how to handle this? Although it sounds bad, I am starting to think about avoiding playtimes with her and I know that other mothers are already doing this.
