We know that Bitcoin is volatile, but it has a high potential for future growth. Bitcoin is truly a good store of value, and the new generation is more likely to choose digital money with all the benefits of decentralization it brings.
Digital money will be used in future everywhere, but it does not mean that we should make saving for our kids in Bitcoins. This cryptocurrency is volatile, and no one can guess its price. better save Dollars or gold. Children will buy BTC for it.
It doesnt hurt (and maybe its even a good idea) to save a small part of what you are saving for your children in bitcoin or another digital currency.
