I stopped having milk delivered when my children were small cos we went through 6 pints a day and it was so much more expensive, now I use 6 pints a week as its only me and my daughter, OH uses soya milk . I think the milkman still delivers to a few so might go back to that.
I hated the milk in the playground too it was so warm and the boys used to make dissgusting noises enough to put you off for life.
