It is hard. We went 3.5 years without a screen at all, but there were times when we both had meetings in the last 6 months (daughter was home with us for the first 3 months) of lockdown that we had to. We are very, very strict with what she is allowed to watch and it is limited to one show only and now that things are "normal", she only gets to watch for an hour or so on Saturday morning.
I have no idea how effective not using gmail is in practicality, but at least it is a sign to people that things can change if enough of us change.
