So my son Andrew and his 4 yo are in our bedroom, I have emptied pockets getting ready for a shower, the 4 yo Kali starts playing with the stuff I pulled out of my pocket and had on the bed, she grabs a couple of bills, a 10 and a 1 kind of crumpled up together, and Andrew chides her for stealing, saying this is serious, you don't take money that isn't yours. I come back with, she is only 4, can't read, doesn't know money from toilet paper and so can't be chiding for 'stealing'. He argues with me saying 4 yo kids know what money is. I never saw a 4 yo yet that knew what paper money is, anyone here see kids that young who knew what money was?
