I read a book that my sister has about potty training that had a short section about "early potty training" that talked about how it could be psychologically damaging to put pressure on children before they were ready and that babies have no control over their bladders or sphincters until something like 2 or 3 years. My sister actually encouraged me to read it because she was worried for her nephew! I explained to her that while I agree with the pressure statement, that its not about that at ALL rather its about learning to communicate about a need, and that regarding the abilities to control bladder and sphincter, well just observe for yourself! I think a lot of people are scared by those kinds of statements from "experts" (who may be getting funding from Pampers? NO! Never! LOL!) which is really too bad. I was surprised at how negative this author seemed and I can see why people would be scared if they didn't have much additional information.
