My DS and DIL have gone vegan in the last year. They are very well informed so I kept quiet about my reservations.
Tonight on FaceTime my elder grandchild explained that the shadows under her sister's eyes are caused by lack of iron and said something about her bruising and mentioned seeing the doctor. I said nothing as I don't want to cause a family rift but my darling granddaughters seem to be suffering because of their parents following a fad.
What can/should I do?
