I’m huge about germs mostly right now and I’ve asked people to only kiss my daughter on top of her head

I guess my family has seen me kiss her cheek and make her laugh so now they want to.

I’ve asked so many times and it makes me mad to keep telling them . She’s 3 months old.

Am i just being to crazy? They kiss my niece in the mouth and im definitely not letting that be a thing with these nasty germs and all so I feel like they are leading to it and I just am so tired of asking them to stop.
