Wet kisses

Sophia likes to kiss. She gives it her all. She will kiss your whole face and tell you what she's going to kiss next. "Eye, other eye, cheek, two cheek, chin..." until she has left kisses all over. It's adorable. Unless she has a snotty nose. She's had a snotty nose for the past few days, and it's not so cute when the wet kiss comes from the mucous kind of wet, opposed to the slober kind of wet. And how do you explain to an almost-2-year old that her kisses come with conditions when it's supposed to be an unconditional kind of love?
