This morning DH and I were having a particularly frustrating morning with our 15 month old DS. He has started to run his toy cars and stuffed animals all over the TV and no matter how much we tell him to stop, take the toy away, remove him from the room, etc., he just continues to do it every time we are in the lounge, which is quite frequently.
After the 3rd or 4th incident, my DH said that he thinks we should start to take away the toy DS is running on the TV and smash it with a hammer in front of him! 
At first I genuinely thought he was joking and I started laughing as it was a bizarre thing to say. But then he got quite defensive and said that DS will stop if his toys are being destroyed when he doesn't listen.
I told him that there is no way in hell that we are going to start smashing our toddler's toys with a hammer and told him it is an absolutely insane thing to suggest. He got stroppy about it and now we are not speaking to each other, as he thinks I'm being unreasonable, and I think he is.
Is this normal? I can't understand where this hateful and violent suggestion has come from. My DH is normally a very calm and loving father, so I am baffled by the entire situation. Yes it is very annoying behaviour from DS, but surely smashing his toys with a hammer is far worse than anything DS is doing! AIBU?
