Search Results: pushing him away

I'm 19, but my little brother is 11. He normally is in special ed classes because of anger stuff. He gets mainstreamed. Last week our parents hired a babysitter. She's 22 and in college. I found out she goes for social work and has interned, and is trained at doing what I saw 2 days ago. I came home and she had him face down on the living room carpet, holding his hands behind his lower back, and sat on him. She had 1 leg on each side of him and sat on his upper legs. He saw me and whined, "Help meeee!"😫😫😫I didn't know what to say and was all..." Uhhh😕😕just push her off.😕" He then tried really hard and that's when I looked. She had on norts, and had serious stretch marks on her legs, she was really thick, and he tried EVERYTHING. Her upper legs and booty didn't move AT ALL. He yelled, " I CAAAANT!"😫😫😫😫I was all uhh... uhh... and I asked her how tall she was, she glared at me and goes, "5'7"😒. She probably weighed like 180!😮I just went😧😧and walked away. She goes😉😉"good choice." He starts going😭😭😭😭😭😭! Later that night, he yelled at me for not pushing her off, helping him. Mom explained his teachers have done that at school when he has outbursts, they're trained how, and the college girl is too. She's bigger than me😕. I saw how humiliated he was. She didn't move AT ALL. What should I do?
