Very interesting. And very brave going nappy free right from birth.

We are doing something similar with DD. She is still in nappies, but we try to look out for signs that she needs to wee or poo and take off her nappy and hold her over the potty mimicking the sounds, etc. We started this when she was about four weeks old and I think its going well. She still uses her nappies, but is also getting used to the potty, e.g. we have only had two accidents of her weeing on the changing mat since starting this. Last week we even caught two poos in the potty rather than the nappy.

I think that going completely nappy free would be very difficult, but I think that this path to "toliet indepencence" as they put it, is definitely possible and worth it if you're prepaerd to put in the effort.
