We use Caribu with the 6 year old, and after a few stories or some colouring in we can get involved in all sorts of chats, she took me (via the ipad) on a tour round her dolls house one day! the 3 year old twins are a different matter, the little boy is very 'in your face' on a zoom call, and shows us all sorts of antics, but his sister doesn't usually say much at all, often refuses to look at us, they are all different! But at the moment the time difference to Aus makes any calls tricky, its 11 hours so when we are getting up they are often in bed already, when the clocks change we can get to do bedtime stories again. In the meantime we chat to our daughter and SIL, the kids show us things. We also send them cards every few weeks, they love getting letters. They sometimes do drawings for us and post them to us. DD sends lots of pictures via Whats App, but we don't have much to take pictures of at the moment!!
