Kissing the baby

I don’t want anyone kissing my daughter after she is born not till she’s at least two months and even then I will only allow certain people to kiss the baby on her head. All I said to my fiancé’s family is I don’t want anyone kissing the baby and his mother looks at me gives me a dirty look and told me she’s going to kiss the baby. I didn’t respond I just talked to my fiancé later but honestly it really pissed me off that she feels like she can tell me what she is going to do to my baby.
