I agree that it is more training the mom to pick up on cues from the child and requires no real work from the child other than pooping and peeing.
However, as someone in the article said, if it resonates, do it, if not then don't.
It just seems like alot of work "catching" the child and having the child "wear" a tiny plastic potty while her mom holds her . .. .I dunno, for me it doesn't resonate and I'M A CO-SLEEPER AND EXTENDED BREASTFEEDER"!!!!
Attachment parenting is what I practice but this just goes to far and doesn't resonate with me.
