Coffee for a toddler?

Ra
I have a friend that is pretty particular about eating organic only and is a big extended breastfeeding advocate (still breast feeding both kids). Her kids are 2 and 4. Today she posted a video of her kids drinking their small Dunkin Donuts decafe coffees. She was tired of them drinking her regular coffee. I was surprised someone so health conscious would give their kids coffee. Maybe it is ok I don't know. Is drinking coffee ok for small kids? Do cultures outside America do it? Not being judgmental just curious about thoughts.
