Well it's not a totally new thing. My mother revealed after dd was born that she had all 3 of her daughters out of nappies in the daytime by the age of 1. She said it was easier to potty train before we could walk because it was harder for us to get off the pot and escape! She is French and said all of her family set great importance on being out of nappies by 1, largely because of all the washing it saved with real nappies. Having said that, it worked for us girls but my brother was a terrible potty trainer. I can remember him hiding behind the sofa to poo his pants rather than use the potty and he wet the bed well into his teens. So who knows...
