That is actually really scary for your mom to do. Neonates are uniquely susceptible to HSV and it can cause permanent catastrophic brain damage and death. Sharing saliva in any baby under 6 months is a terrible idea. It tends not to make the news, but if you search for "herpes" and "bris" from religious individuals putting their mouth on the genitals of children, then you will find plenty of examples. But it's the same reason you shouldn't let people kiss your child: any cold sores (or asymptomatic shedding) can be fatal to your child. Stay strong with your mom. She is lucky that she's unaware of the risk, but the risk is there.
