There are some things that a baby is incapable of really learning and understanding. Until they fully develop an understanding of language primarily and money secondary they need not be introduced to the blockchain. I think really under the age of 5 or so Children should be left to play and learn through fun rather than being subjected to other things.
this isn't subjection, blockchain for babies is just animated illustration of the blockchain technology, so babies get to learn about blockchain while having fun, it's just like teaching your wards how to read the aphabet, in the same vain, this is just a basic or a foundations for which the blockchain idea can be built upon.
