Okay...have to ask the question..how can a child, of any age, be potty trained unless they can get themselves to the toilet on their own?? I'm sorry but if you are trying to tell me that a 6 mo old child is potty trained, then I'm going to tell you that that parent is trained, not the child. I have better things to do than watch for signs that my child 'may' need to poop/pee and then run them off to hold them over the toilet!!! Nope, 3 kids...all made it to kindergarten using the toilet by themselves!!! Until that child has the muscular ability to 'hold' their poop/pee until they can get to the toilet, it isn't ready. And there is no child that can know they are in need of a toilet at the age of 6 months. And no way is a 1 y/o going to be able to 'hold it' for the minute, at the very least, they will need in order to get to a toilet. They just aren't ready.
I fail to understand the eagerness of today's society to deny our children their childhood. It's rush, rush, rush to get them to be more grown-up. Sorry, but poop happens to little kids. You'll have better luck training your cat to use the toilet!!!
