Yes, I agree with LadyGlencoraPalliser.
But I really think it's a case of whether alcohol should be a 'normal' part of life. For some people (not me, I hasten to add) it is.
Teens drink an awful lot more nowadays, not just cider and lager but bottles of vodka before going out etc. It really is a massive problem. And I do know at least one late teen now who does have a massive drink problem and it's horrible to see.
I've got two older children, 20 and 22, and seeing the amount they and their contemporaries drink has really made me look at what I am going to do about my youngest DS. Neither of my older DCs have a problem, in fact DS1 is that interested most of the time, but when they all get together and drink, it's a lot.
If the alcohol is having an effect on their development, hitherto unknown, I would quite like to know about it.
Sorry to be a misery guts but that's what I think, and I really enjoy several glasses of white wine myself.
