Why do people want to touch babies face!!

Seriously. Ive been pretty good with my family about allowing them to see our daughter who was birn at 29 weeks. She came home last week. Everyone but my mother in law and my dad touch her flipping face. I get it she is cute but i have explained multiple times to people she hasn't had her shots yet. She isnt s regular baby and yet they still touch her damn face. I am just beyond frustrated and ready to cut everyone off. Its like okay if she gets sick and goes back to the hospital are you paying for my gas and parking so i can sit with her and the babysitting for my older daughter?

Ughhhhhh
