I have an autoimmune condition and I am pregnant, therefore needing to self isolate. My three year old DS has a cough so we have already been self isolating, though thankfully it seems to be a normal cold. He loves nursery, play dates and all our usual activities. He has good comprehension, is articulate and will soon start asking to go to his usual activities. I am starting to think about age appropriate sensible ways to explain to him why we are staying at home and not mixing, especially as time goes on. I have seen a great video for school aged children but an explanation clearly needs to be far more basic for a three year old. Anyone have any thoughts or suggestions?
