How to help wife and kids remember/store seed phrases for day-to-day wallets?

First, I should clarify that all our keys for our main stack are in air gapped cold storage with backups safely stored. I’d also encourage the use of cold storage and backups (rather than memory) for large sums of BTC or a stack you intend to save for a long time.

This question is for day-to-day use for life on a Bitcoin standard. I want our family and our kids to begin embracing self-sovereignty and self-custody rather than relying on me or custodians. I want us to reward chores with sats and allow our children to have control of their “day-to-day” wallets with small amounts of BTC in for their own spending. Obviously their main stacks will be in cold storage but using something like a coldcard isn’t practical for toy shopping, day trips, etc.

Has anyone tried this with their partners, kids, friends, etc? And are there any good/fun ways to help them store or remember their own seed phrases?

I was thinking of flash cards that had pictures on that corresponded to each seed word but wanted to hear if anyone had better ideas for family-friendly ways of tackling this.

Thanks!
