Yesterday my family and I were celebrating my mum's birthday, and before arriving I had just come out from A&E as my DD (2) had a fall, hit her head and had a concussion in the morning.
All was fine, I was sat on the sofa with my daughter on my lap, she was eating some cake with her hand, and got some icing on it, I didn't mind as we weren't sitting close to anyone. My nephew (19 years old and with autism) sits right next to us, my DD accidentally touches his top slightly and gets a smidge of icing on it.
My nephew starts to gruntle, goes to the toilet to try and take it off, and couldn't apparently. My sister says it doesn't matter, he then proceeds to grab my DD's head and in a jokingly not jokingly way! with his hand on the top and all fingers pressing against her skull! It wasn't a horrendous pressure, but it was still some force applied.
My immediate reaction was to say "excuse me! Do you mind?!" As I tried to take his fingers off, which I couldn't really as there was quite a bit of pressure applied.
My mum says I should have told him a kinder way, but it was an immediate reaction, and thinking retrospectively, I don't know how else I could have reacted.
AIBU I'm the way I reacted?
What would have done?
