my daughter is 33 months old and doesn't really show any sign giving up her diapers. she has clear potty readiness signs, but is rather unwilling to "do the deed" as it were. it bothers me (mainly because she has FOUL poos), but i don't want her to fear her bodily functions.
what appears to be happening with k: she is stubborn. since she was in the WOMB, everything has had to be her way, HER idea before it's worth doing. i imagine, one day, after we all give up asking her about the potty and talking about it, she'll do it, no fuss, no muss, because, only then, will it be entirely her idea.
DD actually started using the potty to pee one week in her 20th month. I made a big deal over it and was encouraging the way I was meant to be.....and she stopped.
Now she is 33 months and just yesterday pooped for the first time. She will only do things when she wants to and although I think we might be approaching this differently if we were in a society without diapers, I am not sure she would go in the toilet until she decides to.
I think this is an interesting conversation and I don't feel judged at all even though I have an almost 3 year old in diapers. It doesn't help that she is almost the size of a 5 year old!
Its simply hard to say how things would be different in a different society or time and its hard to say what is ultimately best for our children - pushing them because there is no choice or letting them decide and having the convenience of diapers.
