Re: Is it too late to start?
I don't think that is too late at all. We started at 8mo (our dd is now 11mo) and we have met many folks who have started later. We have found the infant potty training late starters yahoo group to be a great deal of help.
What is nice about starting with the potty at this age is that they still are highly motivated by making mommy/daddy happy so a little positive reinforcement can go a long way (as compared to an older child who may be a bit more independent). From what I have read about EC at this age it becomes a combination of traditional potty training and EC techniques. Never the less, it is a great age to begin.
