I was facing the same issue here and this was the solution for me: I've created LNbits wallets for myself (instead of using the LND lightning wallet) and the kids... Transfers among LNbits wallets in the same node won't incur in fees. You can connect their LNbits wallets to their phones using the Lndhub extension in LNbits + BlueWallet. Let me know if it works for you!
I love it. I just tested it with lnbits by creating 2 wallets. I could move sats between those two wallets without any issue. Yeahhhhh!! Selfcustody! Bluewallet... here I come. Thank you so much

Good idea. I never tried LNbit wallets to LNbitwallets. Let me try it now! Thanks
