I wait for them to call me because I know how busy they are & don’t want to call when they’re occupied with changing a nappy or on a zoom meeting or something.
But if a period of time had elapsed & they hadn’t called, I’d make an educated guess at what would be a good time to call, and call them.
One bonus with the pandemic was that certainly in the early days they called with sometimes quite irritating frequency to make sure we were ‘complying’ & not going to the shops, or conversely that we were getting enough exercise
