Is it wrong for me to want to cut my mother in law off completely from my kids? Sorry for the lengthy post, just don't have anyone else to vent to.

A little background, my husband and i have been married for 3 years. We have a 2 year old and i'm currently 28 weeks pregnant with our second. The first year or so of our marriage my mother in law was great. But as time went on she began to disrespect me and any decision i make with my kiddo.

One time we had her watch my daughter while i painted our new house, She was there too because my daughter is was very clingy to me. Well my daughter began to cry for me because i went to far out of her sight, instead of comforting my daughter or redirecting her to distract her, my MIL proceeded to yell at her and tell her to shut up and grow up ( my daughter was 1 at the time). This was the first problem i had with her when it came to taking care of my kid, so we cut her off for a few months and slowly let her back in.

Now recently it seems like it's gotten worse and worse! When i tell my daughter it's ok to do something she then tells her right after that it's not ok. And just yesterday we had my daughters 2nd birthday party. Her party has been planned for months. Instead of coming to the party she went out to eat (we had food provided)and she showed up an hr and a half late. We decided not to wait for her and let my daughter open up her presents. Then whenever my MIL got there she was upset that my daughter didn't want to open up any of their gifts, (she was to busy playing) so they proceeding to tug and pull on her arms to get her to come open their gifts, which just made my baby even more upset so she reached her hands up to me to take her away from the situation. And that's exactly what i did! My MIL and FIL got so upset that i took her away. But in my mind my baby has the right to her body and if she doesn't want to be touched or pulled on she shouldn't have to be.

Am i wrong? Should i give her another chance? I honestly don't know what to do. We have been using her a lot to babysit so i can go to prenatal appointments but i'm starting to feel uncomfortable with her watching my kid.
