A little history
Ds1 is 2.4, speech delay, has no words.
He has always been cheeky but things have hit a new level and it's really making me sad. He never listens (hearing checked all fine) always has to touch everything, pull stuff over, climb on stuff. If he doesn't get his own way throws himself on the floor and sometime will hurt himself (very rare)
We have tried the naughty step (just laughs and runs away) time out (thinks it's a game) counting down (sometimes works)
It has got worse since his brother was born 6 months ago. We are totally lost on what to do, as he cannot talk is this the reason for behaviour? I really don't want to turn into a "shouting" parent. I feel like I have failed at being a parent
