Very slick, definitely NOT a charity or NHS.
Says thousands of babies have it and suggests if your baby cries (don't they all) "see your GP". Get the impression they only put that last bit about the GP because they HAVE to.
They say allergy not intolerance . .. which as I understand it is serious and rare.
Never actually say what they're selling though. Private testing? Prescription formula? Snake oil?
Made me feel uncomfortable in the same way as seeing medicine advertising in the USA...
