A sign to warn drivers that children are playing (and might, for example, chase a loose ball into the street) is a good thing. This sign, though, is a bit confusing. If the children are playing on a seesaw then they’re not running into the street. Unless they have a portable seesaw that they set up in the street, in which case there are problems bigger than traffic. Maybe the intent of the sign is to encourage drivers to park and go play on a seesaw, but that seems unlikely.
