Add some puffed amaranth to the bottom of your two glass and top with a couple of tablespoon of yoghurt. Top that with half the mango and then repeat to create another layer. Top with passionfruit and serve.
Notes
Puffed amaranth is also called popped amaranth. I haven't given exact quantities because you can just add an amount that suits you. For tiny babies, puree the mango rather than chop
