Elly votes for the “hedgehog” approach suggested by Peter & John B.

I, however, having grown up in a house with a mango tree in the garden, would like to point something out. There are different types of mangoes. A key distinction is between those with fibrous and flat stones.

The ones that are insanely difficult to destone tend to have fibrous stones — like Kling peaches, these are VERY messy to deconstruct. If the little person is a real fan, perhaps you might be better off trying to find a source of flat stoned mangoes 🙂
