My son Henry was a lovely newborn baby, but we noticed that from about 1 year old he developed very dry skin and nasty rashes all over his face. We tried lots of different things until one day, out of the blue, we were told to cut out dairy products. The dryness and rashes disappeared within a fortnight.
Henry was very adaptable, and loved eating goats cheese and drinking soya milk, but it wasn't until he tried goat's milk that his eczema went without a trace. Although we hope that he will one day be able to have dairy, I don't think he'll want to give up goat's milk - having different milk to his brother is too much fun!
