It's actually something that's normal in most of the world. Takes a lot of parental dedication, and it's not something our family would do well with, but it's not unreasonable or totally impossible.
Actually this is not easy. I do this with my two year old and it's been going on for six months now. The outcome is she tells me that she has a prize in her diaper after the fact. I believe I have confused the child be constantly asking " potty" "potty" "potty" 100 times a day. Anyway she still poops in pants and then she says, "it's disgusting". LOL
Which is perfectly fine...if one of the parents will be with the child day and night to learn the signs and be there to take the baby to the toilet.
In todays society here, which parent will be the one to give up their day job and at which point does the family file bankruptcy?
