Hey, the Lightning Address in Alby Go is only used to generate QR codes - still the LN address service needs to be configured somewhere. You could generate invite for your kids to getalbycom, there they can set up the Lightning Address and put it in Alby Go.
PS For this to work, both Alby Account (getalbycom) and Alby Go need to use the same NWC connection secret to your node!
Thanks for good feedback!
