What age did you start drinking coffee?

My 14 year old daughter surprised the heck out me this morning when she pulled out our coffee maker and made herself a cup of coffee.

I’m not a coffee drinker and her father only drinks coffee at work. We usually only make coffee when we have overnight guests.

She had a bit of coffee some months back when my brother-in-law was visiting.

I’m not sure if I should kibosh this as she is 14.
