My son is three and tested positive yesterday. He was in contact with a positive case at nursery last week (isolating since Thursday) so we're not too surprised, he's doing ok so far.
We haven't been following the public health advice, I mean obviously he washes his hands and all that, but we are not keeping him separate from the rest of the family. He's only little, he wouldn't understand, and we have three children aged five and under in a small house, so it's just not possible. It's a risk we have accepted we are all taking, but I'm not making a poorly three year old eat by himself and not give him a cuddle etc.
Anyway, nobody else has symptoms yet but I expect we will all get it. I wondered if a member of your family tested positive and you didn't keep separate from them, did you all get it and how soon?
