I know that i have done this to death, I have a dd 2.8 years and have studied Psychology to post grad level, so have a keen interest in child development especially in relation to potty training and the concept of 'readiness' A lot of people on MN feel that this is a fairly new phenomenen, but talking to my older relatives about it, seems to me that its not, and that parents have been waiting until the toddler is ready before starting potty training for years, I know that my mum did 30 years ago, and my mums cousin did 40+ years ago. I have a Dr Spock book, and even though some of the advice that he gives should be taken with a pinch of salt, even talks about waiting until the child is ready, and I think that he wrote his books in the 1950's but have been adapted for modern day reading.
For me personally, waiting until the child is ready is the way to go, I have tried on two occasions and dd is not ready and have failed. I feel that no amount of potty training will work unless the toddler shows signs of readiness, and thus are in for a long hard slog. It seems that those parents who wait until the child is ready have a fairly straightforward and easier time. I thow it open to you here, what do you think!
I might even do this as a future study once i get back into Psychology
