I don’t know how to stop people kissing my baby. I have told my mother in law 100 times not to kiss him. And she still does probably even more so since we have told her not to. He is now 9 months old and people are still doing it. The other day we were out somewhere and my husband’s grandma had a random kid and her kissing our baby, my husband immediately said no and his grandma was arguing with him saying it’s okay I don’t have cold sores, my husband said I don’t care we don’t want you doing, and she continues to argue with him, I don’t know how to get people to respect us. When we have told them 50 times. I would never kiss someone’s baby so I don’t know why they do.
