Hope you find a solution that works for you. The sensors, like most electronic devices, are continually being developed and improved.
I'm not sure if the libre has this option but dexcom allow allow the wearer to have at least 2 'followers', which for my daughter is myself and my wife. I can log in and monitor her levels from wherever I am, as long as her phone is within range of her sensor.
I'm at work, she's 20km+ away at home...
It's great for parents. Can set alarms for low and high levels etc
