So, E has not miraculously turned into a toilet using toddler, but...he is eager to use the toilet/potty chair. A big upside is that - instead of being diaperless most the day, sitting on the potty chair most the day, randomly sitting, not potty-ing, etc - E actually told me he had to go "boop" (mind you, this includes potty) and so I put him on the toilet. Amazingly he MADE himself go - not just it happened , but he actually sat there for a while and made himself go (with intentional effort). This is most definately a good sign. Not to mention, he did it again today. I am VERY excited. Diaper free might not be too far off.
