Grandma kisses???

Hayley • 25, mommy to Milo 👦🏻💙 and Ollie 👶🏼💗

So we currently live at my MILs house, and we will for a couple more weeks while our house is being painted. My baby was born on the 25th and we told people no kisses. It’s almost October (flu season) and my MIL smokes. She was fine with no kisses but I think she saw me give him kisses and now that’s all she does. I don’t know how to tell her to stop, help!
