Milk makes me violently ill...
And after a few decades, it may be wheat does too, and I was just never tested/checked because the Drs said "oh, you just have a cold/are lazy/what you moaning about?"
So I have zero confidence in such a law to be use balanced or helpfully, but instead to cause loads more harm then getting a little less milk would do to a person. :/
But no doubt the intention is to make abuse and neglect illegal... which tends to already be the case, but people need it spelt out I guess?
