MrB burnt his hand on the vaporiser this morning. I turned it off as soon as I saw him look at it. Quite a few minutes later he made a dash for it and I wasn't quick enough. Feeling soooo bad. He's already so miserable because of the virus. Should I take him to the doctors or just get something at the pharmacy?
