Sorry to hear of that. In future, if he goes to kick you, just leave him to it. It's hard but he is refusing your attention. You would not be blamed after that for leaving but persistently offering care they will hold against you!!!
I remember being bitten so hard that I had a six inch purple bruise on my arm. All I did was hold the man up so he didn't fall and he sank his teeth in as I transferred him to the bed. I was told I should have just let him fall. No support was given, I was made to feel embarrassed. The family apologised for their dad which was nice.
