If you have a ColdCard you can use a BIP85 seed to start putting sats in now. Set hers up with it when you give her one, and tell her you have a backup (and of course to never enter it anywhere else). Encourage her to make her own when she's ready.
Thanks for the advice. I don't have a ColdCard yet, still using Ledger. But I plan on getting a ColdCard soon.
