Tutorial about hydration of babies.

I was looking for how to make homemade saline, and I came across this digitalised medical article, in this section it teaches a technique of how to teach visually the way that a healthy baby looks like and on the other hand, how a dehydrated baby looks like, we draw the baby in both bags, fill them up with water and dig a hole on the bottom of one of the bags.

I thought that it was a pretty strange image, something coming out of the darkness corners of the internet, however, it's just a innocent health tutorial.


Here is the link for the article I mention.
