@...Sikras: Actually it’s surprisingly common among children who are learning how to write. You can write the word down in front of them and let them copy it, and they’ll still get letters backwards. b/d and p/q are the most common but it’s not unusual to see backwards c’s and e’s. And that’s amongst kids who are already getting the hang of reading & writing, which those two look to be a couple years shy of. So if you consider spacial recognition and hand-eye co-ordination to be “basics of human thought”, then yeah, kids don’t got that.
