Liam has a cup of diluted Barker's blackcurrant juice for breakfast & then it's water for the rest of the day. I always try to remember to brush his teeth after breakfast. I like the idea of him getting a bit of Vit C.
No fizzy drinks in this house though. I'm sure it'll help that DH & I don't drink them. I remember having Sprite at my Grandparents house when I was young & it was a huge treat.
Fleur, I think it's something to do with the fact that bacteria can grow in the plastic bottles - or it could just be a cunning ploy from the drink companies to get us to buy more water...
