Norton Online Family vs TeamViewer

I use Norton Online Family for about 5 years (since it was called Norton Minder)... About for the same period of time I use the TeamViewer.

Until Norton Online Family update Autumn time last year I was able to connect remotely to my computer running Norton Family, but that not available any more...

A lot of times my girls are home with a babysitter and they want me to connect and show them how to do this or that...

Does anyone has any ideas how to endorse Teamviewer thru Norton Online Family? Thanks!
