I did see a mum on social media who had one of her identical twins medically tattooed. Apparently it's done under light sedation and the tattoo looks like a small freckle. It was to avoid confusion with medication etc but she still received very mixed comments.
That poor mother, she would soon be criticised if one of the twins received the wrong medication due to them being identical.
I am beginning to think that social media, X, Facebook and forums like GN, MN are giving folks platforms to be judgemental on all and sundry?
