Why do kids write some numbers and letters in mirror image?

Question

I’ve been practicing the ABCs and 123s with my son and notice that certain letters (J N P S Z) and numbers (4 6) he always writes backwards/mirror imaged. I’ve seen other kids, and even my own writings as a child, have the same quirk. Is this pretty much universal?

A lot of kids do this. However, it can also be a sign that they are left-handed. This can be tested by encouraging a child to try to write alternatively with either hand.
