I never had it as my mum put me straight on cows milk in a beaker when she stopped BF around 6 months so I never even had a bottle, but my brother was given a bottle as she returned to work a bit earlier (and she didn't get him off them till he was 3/4!) and yeah he had tea in it, quite surprising really when my parents were pretty strict with food etc growing up. My eldest is 4 and he's never tasted tea nor has he asked for it, I don't drink it but DH does, I just don't see the need in giving kids tea but there are worse things, but I don't believe in putting anything other than formula in bottles. I squirm when I see squash in a bottle.
