Help

Hey ladies I’m in need of help! My son has suspected adhd and autism and he also has epilepsy.. so safe to say his emotions get a bit wild. He flips out and has no problem hitting me. He’s 5 so atm it’s not bad but sometimes it really does hurt. What can I do? Like tonight for instance it was time for bed and honestly I dread it every night. But tonight he went full mental mode kicking me, slapping me, trying to boot my face. I’ve tried being nice and getting on his level, doesn’t work makes him slap me more. Anyone any ideas?
