Icons and text (daycare) for "pee pee" and "poo poo" without being gross?

Question

I have buttons where the daycare worker can select that a child went to the bathroom. They choose whether they "pee'd" or "pooped" (or however you say that in a politically correct way). I want to show icons for those while being respectful and not totally gross. I also want to show the words underneath and I cannot decide if writing "poo" and "pee" is professional. It is for daycare so that might be legit.

Answer 1

how about #1 and #2?

Or from the noun project:

this icon for drops labled #1

and

this icon for poop labeled #2
