So I went through the comments yesterday and set up LNBITS with LNHUB extension. I already had a node so it was just couple of clicks and I set up a test BlueWallet. Interesting that when you send sats from your node to the test BlueWallet the balance on BlueWallet shows sats there, but in reality your lightning node balance doesn't change. So really like a bank for your kids. Can recommend:)
