DD, 9, had a sip of my tea yesterday and said she liked it and asked to be allowed to drink some more often. I'm not sure. It was after walking back from an activity to the car, so I'm inclined to think it was a warm drink she was after rather than "tea".
I let her drink fruit "teas" which are technically infusions, but not black tea or coffee.
AIBU to think she is too young for proper tea? My main concerns are caffeine, teeth staining, iron absorption.
YABU: let the poor child drink some tea!
YANBU: She is too young, no tea for her!
