No advice but just want to say you are not alone.
Ds scratches, bites, hits and pulls hair. He is nearly 3, and is aggressive whenever he can't get his own way or when I tell him no. Flash points are getting dressed and getting in the car seat.
He used to hurt other children in social settings, but now most of this behaviour is now mainly directed at me.
I've no idea why, we have never smacked him, and don't hit each other.
When he is aggressive we cope by saying no, thats not nice, and ignore him for about 10 secs or so, before turning back and and carrying on talking to him in a normal way. This so far has been the best way of keeping things calm. We have tried timeouts which did use to be successful, but now it escalates the the anger. If he bites/hurts and we are at a park/somewhere nice we leave immediately to try and enforce that there is a consequence to such behaviour.
Don't know if I agree or not with the toys in the bin. I know I have threatened it, and it has been sometimes enough to stop the aggressive behaviour.
Any chance that this hormone surge could come early? Like about a year early?!
