From a youngish age (maybe 10-11) I am going to let DS have a watered down small glass of wine with dinner - I don't agree with "Mummy can have this but you mustn't touch it." You have to lead by example and I intend to teach responsible drinking. That way he's tried alcohol before it's an issue and he may not like it. I won't get in the alcopops or larger, it will be "proper" stuff only (wine or a decent bitter - not spirits!).

I had my first hangover at 10m old, not what I want for my babies!

BTW, in the UK it's only buying alcohol that's illegal until 18 - you may drink at home or under parental supervision from age 5, in public (indoors) age 11, outside age 16.
