Why was ale the only drink for children in the 14th century?

In the 14th century, ale was often the only safe beverage for children due to the poor quality of water, which was frequently contaminated and could cause illness. Brewing ale involved boiling water, which killed harmful bacteria, making it a healthier option for hydration. Additionally, ale was low in alcohol content, making it suitable for children, who would consume it in place of water. This practice reflected the cultural norms of the time, where fermented beverages were commonly consumed by people of all ages.
