It didn’t come together like a granny knot, which I understand to be just a square knot with the orientation of one half flipped. The knot I learned wrapped the free end around the base of a loop and pulling a section of that free end through it to create another loop. It was unbalanced for the same reasons as a granny knot though and probably very similar.

The knot I tie now is basically a square knot where the “top” half is formed from two loops. Admittedly the knot I tie now, would have been much more difficult for toddler fingers than the knot I learned as that toddler.
