just asking would anyone Teach there baby to start using the potty at 3 weeks old?

I was looking at some Lady ticktock she say all her kids were started potty training at 3 weeks old. Most of them were fully potty trained by 3 months. Go to the details that she started training them so young so that she doesn't have to deal with diapers. in one of her videos which I kind of felt it was wrong that she was even using her children for a tick tock. But she pretty much shows what she's doing with her baby who is literally under three weeks old putting him on a potty so he gets used to the feeling of peeing in a baby toilet an not in his diaper. She says hopefully by the time this kid is 9 weeks he's fully trained. It's apparently from what I seen she has six kids . all her kids have been trained the same way. My question is would any other parent train their newborn baby to pee in the toilet by the time they were 9 weeks?
