Joanna Fortune: My granddaughter doesn't want anyone to know about her alopecia

"Sometimes, when a child says not to tell anyone, they want to control how often and with whom they need to talk about something they find challenging."
What a lot of stress you and your family have been through this last year. I am happy to read that your daughter is recovering well from her illness, but I am also aware that the stress and worry caused by a loved one being ill can linger long into recovery. Go gentle with yourself and each other while you all recover from a worrisome experience.
