Have you watched Adolescence?
Do you know what he’s viewing on his phone?
if you both work full time when do you ever get to sit down and have a real conversation to ask him how he is, how he truly is? Or do you just assume everything’s fine because he says nothing? Or, “I’m fine”.
It’s a skill to get some kids to open up and parents often don’t take the time.
They leap in with taking the phone away or grounding, never really getting to the bottom of what is really going on.
Talk to him, properly. Find out what’s going on. There’s so much more to this.
And if you really want to help, talk to the teacher involved. They didn’t give him a detention for fun. Something happened. Find out what’s your son is doing. There are two sides to every story. Work with the school instead of questioning on Mumsnet if they’re an appropriate punishment.
Also you need to teach your DS that pushing women is unacceptable and that he is not allowed to touch women in this way. Especially women in his family. Is this how he’s going to treat his future wife?
If he does it again, tell him you’ll call the police. How do you think domestic violence starts. Someone, somewhere, doesn’t teach boys that grow into young men, that violence towards women is not ok. Your DH also needs to step up and tell him how men behave and it’s not pushing women around.
