PISSED AF WITH MIL

My bb is 6 months and recently she is in the separation anxiety phase/ learning about object permanance. Recently, she was ok if we left her for a while to get something quickly but now she needs to be able to see us then she won’t cry. I know my husband knows and everyone with a brain knows that it is normal and this phase will go away. But a while back, when my bb met my MIL initially she was ok being carried by her but two hours later my bb got tired and didn’t want to be carried by my MIL. She attempted to carry my bb many times but my bb cry whenever my MIL hands out her hand to carry my bb. My husband and I told her “bb is tired..she want to sleep” but MIL kept on trying. Even when my husband relative said, “leave her alone…she quiet you disturb her again and again then she cry” but my MIL stubborn af kept on trying again and again and it really upset my bb to the point that my bb cried so badly. She was unconsolable. It never happened before. My husband brought my bb to somewhere quiet in the house and thats when my MIL said in front of the relatives loudly and rudely, “ya la always never come here she dont recognise me”. In my head I was very upset because these kind of things why must say infront of outsiders, can tell her son what. And also, we come once in every two weeks. I think thats often, cos my husb work shift and sometimes his off days we just want to be together as a family and not visit my MIL. Strictly just family time. I knew why my MIL said that its because she is bitter that my fam takes care of my bb. My mil works so her taking care of my bb is not even an option, even my husb think its best my bb is taken care by my fam. But of course we didn’t say all these to her. But my MIL has always been a pain to me from the moment i have my bb. I keep quiet cos I didn’t want to ruin the relationship. I shut my mouth over many things. Many many crazy shit happened to me. You will be mortified if you find out. Wish I have a friend to rant to LOL. Anw, I take in a lot. I never once talked back. But I felt that shaming me in front of relatives is too much. So I told her in front of everyone “my friend child is also same age and in the same phase” her relative also said in front of her “its a phase the bb will be ok after this phase” “its normal”. I then purposely said loudly, LETS GO HOME. Baby crying non stop already to my husband. And then we left. I cried on my way back home. My husband didn’t know that happened as he was somewhere else but I told him of course his mum is smart to say it when he is not around cos he will tell her off. Anw, the moment we left the house my bb kept quiet. I just wanna know meeting in laws, once in 2 weeks too little? My fam gets to meet my bb cos they take care of my bb and i send her over everyday????? also, i want to make sure my MIL knows im pissed at her, what can I do? I had enough. I tolerate TOO much. Wish I can tell her to shut the f up. Always have some negative shit to say about my bb and me.
