DS1 only if it is a very dire emergency. Doesn't trust any form of electronic communication, and won't talk on the phone, but will one in three times respond to a Signal message. DS2 sends lovely messages maybe once every few months, will call back if you leave a message. Lives locally, but we hear more from DiL than him, when she wants to give a present to one of the others, as they are too frightened to see anyone at the moment.
DD we have been seeing twice a week for homeschooling DGs, before then I would collect DGS from school, cook them a meal and take DGD to ballet afterwards. DD is very excited as picking up a new puppy at the weekend, so we get sent lots of photos.
DS3 is the only one that will ring for a chat, perhaps once a fortnight. We have family WhatsApp and Signal groups (DS1 won't use WhatsApp) that spring into life if any one has news.
