Don't know that what I eat has anything to do with my grandkids as they are all adults
and I certainly don't question what they eat. I have reached the age where I eat for
enjoyment, my diet has always been fairly healthy, so if I indulge occasionally and have
to pay for it, I only have myself to blame.
I don't have grandkids but my oldest great-niece would eat nothing as a child but mac&cheese and Chicken McNuggets, neither of which I will touch ...
Her grandparents (who basically raised her) didn't seem to make any attempt to make her eat fruit and veg.
