Great news I say! The WFTC screwed up our initial application so we never got vouchers when ds twins were on formula milk, but all of a sudden, after they noticed we weren't getting the right allowance we now get milk vouchers. I must admit to being a bit embarrassed until a friend pointed out that up until I had had the boys I paid a fair whack of tax (worked from age of 16.) Still, there is a stigma attached to the vouchers.
I wonder if it is £2.80 per child as,like Twiglett said, it won't get you much (even in West Lothian, it is a lie only Londoners pay more for everything!) The hobbits have a voracious appetite and love their fruit - veg on the other hand needs to be hidden!
