Paul and I are trying this potty technique, elimination communication (EC) with our baby. So far, it's going pretty well.
We're hoping that taking our baby to the toilet will mean early potty training, but I recognize that the book specifically says that's not the point--communication with your baby before they can speak their needs is the point.
The book gets one star knocked off because about half of the content is quotes from other parents who are all like "we were skeptical or so-and-so was skeptical because of this and that, but then we tried EC and it was great."
Overall, though, I think it's a great idea, and I like the encouragement that you can just try it sometimes--that anything at all helps to maintain your baby's mental connection between the feelings in their body and using the toilet.
So, we're just trying by giving her opportunities ("pottytunities") to go, and hoping we catch most of her poops. Makes clean up way easier so far.
We also don't let her go totally "diaper-free," but have a cloth diapering service for now, which helps. Supposedly cloth diapers still feel wetter than disposables to a baby, so it helps them not to lose the connection between their brain and the sensation of going to the bathroom.
Hey, at least it's something to do when you're stuck at home with a baby during a global pandemic.
