You couldnt even start school not house broken when I was a kid, nor my kids.
This is just one of the many memes that teachers perpetuate to gain sympathy and higher wages. Granted, it’s a new one. It doesn’t add up to me. Diapers are expensive and parents work to get their babies out of diapers as fast as possible. To my knowledge, there are no government programs that pay for diapers and even if diapers are paid by food stamps, these welfare recipients don’t want to spend their food stamps on diapers.
It’s still that way in some places...the story could be BS.
