Plain and simple, kids are gross. They are smelly, sticky little monsters.
Ever since my son started eating real food (not baby food, but self feeding actual food) everything is sticky. For a tiny human who can’t walk or properly crawl yet (he is more of a roller at this point) he gets his dirty little hands on EVERYTHING. And he hates getting his hands or faced wiped.
I can spend the entire day cleaning and you’d never know.
