need advice about a kissing sil

Looking for advice. i won't be offended if you tell me I'm wrong. this is actually my second post about this bc since then it got worse. my baby is 14 months. every time i see my sil which isnt often, but a good ten times, I've asked her not to kiss my daughter in a nice way. anyway, that's why i posted last time. fast forward to today, im sitting there and not only did she kiss my daughter, SHE KISSED HER ON THE LIPS! she canceled last week bc she was sick which makes me evenmore pissed! so i jump in and say, "no not on the lips! we don't kiss on the lips!" She just gave me a stunned look and not too long after she left. while saying goodbye she kisses her on the cheek again! i swear i was gonna lose it. right when they drove away i gave my husband an earful and now it's caused friction. i feel as if my husband didn't stick up for me and tell her no in the first place, so im the bad guy again. the both of us never kiss her on the lips and i tell my family (even my mom) the second they come in and they listen. . his family never does! she'smy daughters god mother so i don't want to rip in to her, but im so tired of this bullshit. i dont want any kissing of the face at all, nevermind the lips! i even told her about rsv and other sicknesses with kissing so that conversation is pointless. i don't want problems with family, but im tired of being walked on in my own home. what would you do? im going to show my husband all the replies... thank you
