childhood illness

Here is what I did use. Her scabs were practically gone in a week, we're now four weeks on, and while she still has a few crusts in her scalp, her body only has the tiniest of pink dots left over, and as far as I can tell she has no indented scarring anywhere on her face or body.
In an ideal world the minute that a child is unwell or unhappy we would drop everything and tend to them completely. But it is not always that easy, especially when one is self-employed.
How on earth can cow's milk be considered an essential part of our diet when its purpose is to feed calves until they are old enough to be weaned? How does it make any sense at all that people are supposed to have it? Just because we have been doing it for centuries does not mean it is rational or good for us; it just means it was an available food source at some point, and has since become an acceptable part of the human diet.
