My in laws are grossed out that I’m pumping.

So we were at my in laws last night and there is really no where to go to get privacy except their one tiny bathroom connected to the kitchen and family room. I have an oversupply and so I have a willow go for pumping. I usually use my breast feeding cover to put it in so that I don’t flash anyone but I had to adjust a few times last night. So my mother in law called my husband and told him at first that she wanted me to pump in a separate room away from everyone. He stuck up for me and basically told her that isn’t going to happen. So now she wants me to go and get all set up in a different room and then I can come back in where everyone else is. I’m still frustrated and embarrassed. I don’t really want to go hang out with them anymore. Which sucks cause my husbands older brother and his family are visiting for the first time in 5 years but it’s always something with her.
