Can a court make you stop breastfeeding ?

So my youngest is four months old I made the decision about a month ago to divorce her dad. Long story short she is bipolar and was abusive for five years. He has his crazy mother on his side, trying to control things and she’s claiming that if it were to go in front of a judge, they would force me to put my daughter on a bottle. For context, I breast-feed exclusively and have been attempting to get her on a bottle for a while, but like with my oldest daughter, she just won’t. I’m also hesitant to do so, because as long as she doesn’t take a bottle I can make sure I’m with her and she’s safe.
