Steph would always swipe my teas (and coffee!). My brother and I grew up drinking tea, not sure from what age, but I have a photo of me drinking it when I was about four.

I don't think the caffiene is very good, and I'm not sure what else there is. My Mum also said something to me about 'caffiene free', and the way that it is processed, it could be 'worse' for you than drinking the caffiene.
