He'll be 3 next week. He has GDD so he is still at a 2 year old level in his physical development and slightly younger in his menatl development.
He is happy, fun loving and a very cuddley, emphatic little boy but he has recently started to lash out with intent rather tahn just being unable to control hs movements.
I get the brunt of it and I was in tears by the end of yesterday, mostly with exhaustion but also with a sense of despair. I have tried ignoring. Holding his arm and saying "no". Putting him on a "naughty chair".
He grins and laughs at me and hits me again.
He also hits the other boys, DS3 has a bruise on his forehead from DS4 hitting him with a beaker.
What's the best course of action to take in your experience?
