Thanks again for your desire to contribute Zoë. As with some of your other notes I will say that the notes feature here is for requests for changes and additions to the map, not general info about a location. 

I'm editing the map based on the fact that you point out it's an open field. I retagged it as a sports field, with the name "Dhulikhel Stadium", so you should see it show up as green on most maps now. The name was already mapped so I didn't need to change anything there.

The info about kids and teenagers can not be represented within the OSM data, nor would I think it could on most maps.
