“Etiquette rules” for visitors during breastfeeding?

Hello,

I’m EBF my 4 m/o, and in general I’d say I’m pretty comfortable nursing in from of friends, family, and sometimes in public. But my boundaries have occasionally been crossed before I even knew the boundary existed, for example MIL kissing baby on the cheek WHILE HE WAS LATCHED. I didn’t think I would have to specify to NOT put your face so close to my boob while nursing, so here we are.

Next week my BIL comes to visit. He is my age, autistic, and bipolar, and has some ingrained misogyny that comes out when he gets heated. He has said some really horrible things about women, some specifically targeted at me, ie calling me a slut. This is by far not the norm, but it has made me want to prepare for his visit and how I want to approach nursing while he’s here.

As I’m typing this I’m kindof realizing that the best solution is just to remove myself and baby to another room. But I think I’d also like to have my husband provide him with “rules” in case I do need to bf in a common area, for example no comments about my body, no sexual comments of any form. Has anyone ever come up with a list or guidelines like this for people with, erm, questionable social boundaries??
