I want to give an fun tip and that is, PIGGY CRYPTO BANK. And you said absolutely true about the teachings of money to children in young age only, and we saw in many cases where due to lack of teachings when children grow up they take money as granted and this situation can prove disastrous.
And if children get to know about the importance of money then they will showcase responsibility towards handling the money and also they can pass this chain of teachings and responsibility to coming generations.
Wishing you an great day and stay blessed. 🙂
