They change shape due to a number of reasons.
The easiest reason to understand why they change is that they erode.

Of course, the entire modest proposal was that parents eat and sell their children as food and the idea was meant as satire, meaning to be considered with a grain of salt and not seriously (kind of like a really dark joke).

Hope this helps! :)
