If you looks at the small grouping of berries and the small white petal flowers with yellow stamen it looks very much like it is part of the nightshade family (which covers tomatoes and potatoes as well as deadly varieties etc). However the leaves don’t quite look right for that as they would normally be pointed.

Firstly I’d tell the kid, don’t eat shit that you know what it is. Second they should use an app to try identify it.
