Family members kissing baby on lips?

Sweets • First baby due December 13th, 2015 ❤️
How do you handle this or am I wrong to think this way. My baby isn't even born yet and I'm thinking of how I'll handle this. I know it's going to come up with my mother in law because she kisses everyone on the lips. (Not me because I turn away). But I can't have her kissing my baby on the lips. I've read that most people who have  herpes type 1 (aka cold sores) got it from being innocently kissed as a child by family members.
