I don't think if that is good idea to learn your daughter using dogecoin and how do you teach your daughter about dogecoin.. how to transfer? to gamble? collecting doge?.. In my opinion it is too early for your daughter to learn about cryptos, it's not the right time maybe when she's teenager.
Indeed, the children's developmental foundation does not belong to crypto knowledge, it belongs to knowledge in school and what they learn from life, so the idea of talking about dogecoin is not necessary, it is not really a topic that we can discuss with the kids, unless they are a special talent but this is very rare. Besides, the excitement of our era will be much different from their own, sometimes dogecoin will no longer fit and be replaced by another project, time will change many things very quickly, kids will have a path to exposure to crypto, they don't need our instruction too soon.
