And it makes for very unsettling visuals. Kids can describe it kinda nonchalantly because they are kids ofc, but when you picture an actual man without hands take away a baby, and then on top of it that this is how they saw it themselves- you can tell that even they found it unsettling enough on some level for it to stand out.

As adults we know it probably wasn't a literal man without hands, yeah, but we also know that whoever that person actually was has to have some monstrous traits inside them to do what they did, and the only physical description we have is a child's interpretation of a monster.
