Anybody else not trust their mom with their child

It might sound horrible but I dont trust my mom at all with my daughter I would rather take her with me to what i have to do than let my mom watch her. My reasoning is cause when she was a baby this psycho took me telling her not to give her cold milk as a okay to make it with hot water luckily I caught it and corrected it before she got hurt! And my aunt had witnessed her screaming at her at just 4 months old for dropping her pacifier too much. The biggest part is from when i was a kid she would hit me all over my body with a belt and it wasn't for just doing stuff i wasn't supposed to! She believes kids should be seen not heard so while a child is playing they should be perfectly silent. She has displayed signs of treating my daughter that way like she took her box of toys out of the living room and put them in her room and if she takes out more than a toy or 2 she screams at her to put it back. She doesn't allow her to dump out her toys and if she makes noise she screams at her to shut up! My daughter wakes up in the middle of the night most of the time after im asleep and i have woken up to hear her telling her "im tired of your s**t lil girl" I have cussed her out multiple times for how she talks to and treats my child and it dont seem to do any good. No i dont live in her house she lives with my fiancé and I cause she will literally starve herself and go without her medicine unless she has someone to take care of her. Im honestly getting tired of her behavior and sadly almost to the point of not caring about her anymore! She always tells people one side of the story and makes me to be the bad guy so people will feel sorry for her. Just like what happened today im sure when i go to my grandmas ill hear about how i screamed at her for no reason and called her stupid. When the real story is she was yelling at my daughter so she started to leave her room to come to me n in an attempt to keep her in the room she slammed the door shut and nearly knocked her out with it! So of course im gonna scream my 2 year old has a giant knot on the side of her head!
