i never even thought of trying that!!! the idea is amazing, after all, we all do as we're tought at first! skipping diapers all together makes sooo much sense! my son has autism so im finding it very difficult to potty train him now and he's pushing 3yrs this coming jan! for those unaware, autism affects the ability to communicate, so if i would have tried, or even better succeeded, at such a young age that would have been the greatest help to me!! im already on it attempting with my 16 mon. old daughter just wish i knew about this sooner! i highly reccommend any parents attempt this method, especially because of the high rise of autistic children being born today! you really dont know until they're about a year if they could be developing slow for any reason so potty traing from near birth actually can be nothing but beneficial to you , your pocket book, and of course Baby!! me as a single mom can't thank you all enough for sharing this information!!!
