Something I have noticed about splash parks in my daily trips.
The kids love them too. More precisely they love the jets that shoot from the ground.
Where there is a jet, there is a little one squatting or sitting on it and an embarrassed mom gently trying to shoo them off without drawing attention to herself.
The kids line up, waiting their turn for a jet squat. My darling little Jonas is a jet hog. He doesn't let anyone else have a turn. Apparently he has discovered that a nice powerful stream of cool water feels good on the junk. I am the embarrassed parent who gave up on shooing him off and just sits on the bench mortified, yet trying not to snicker.
