I learned from my middle eastern mother to potty train my kids from birth using the sink and later potty for them to wee and poo. This has worked so well, My DD was potty fully trained before 2 but doing poos in the loo well before this. My DS is now 9 months old and does most poos in the loo on the toilet seat. He goes on first thing in the morning and then after every meal and every sleep. We have the odd accident, but not really. I haven't found any information about this and no one I speak to has ever heard of such a thing. I am wondering if there is anyone who has done this and would like to share experiences.
