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.
it's too early to introduce blockchain for babies.
because the world of children will know everything naturally and by seeing things done by other people or parents, the child will also know automatically, this can happen to the world of buying and selling and especially payment instruments, they will find out by looking continuously continuously.
so everything will run naturally.
