If you're giving bitcoin to your kids or sorting for long-term, don't keep it in a lightning wallet/channel. Put it in an on-chain address using a wallet like Aqua etc.

Oh they have btc in cold storage, I was thinking more about having a lighting channel for each of them to be able to transact cheaply in the next 10 years.
Nope. The chances that happening with a random lightning node as your peer is so low you have a better chance of getting struck by lightning while being bit by a shark under a full moon.
Only way to do that imo successfully, is to run two of your own lightning nodes, and open a channel between them just for yourself.
Would you recommend Alby hub for this or should one just not worry too much about managing lighting channels? Perhaps ecash, liquid or other implementations will be good enough in the future for micropayments.
The dirty secret is we might actually blow up lightning and move to something else. Who knows.
I'd say for now;
• use your Lightning node as a family node
• give your kids an LNBits/Alby/BTCPay/etc. account for them to stack/spend
• ecash would be great (run your own mint on your node [too easy with LNBits]) and give them that
- today's ecash is basically offline, more private lightning
When their balance gets above ~100k sats, use Boltz to swap that lightning, to a UTXO 💜
