I need some help/advice

Leanne
I'm due in 3 weeks 
When my baby is born im planning on ebf my baby, my mother in law has just informed me that her daughter (the babies auntie) is home for a week when my baby is 3weeks old so she will be taking it for the days and bringing baby back on a night so I better get used to expressing or formula feel a) I don't want my baby to have bottles so early on b) I don't want people taking my baby c) I don't feel like I can say anything and last time I mentioned something she laughed at me and basically called me stupid, my baby isn't even here yet and to be honest this is making me feel like I don't want to give birth coz if baby is inside me no one can take it!!! I feel so sad
