I heard many, many recommendations for Potty Training in 1 Day. I heard it was all about commitment. I was promised if I followed it, life would be good. I was a little desparate because the only pre-school that I could get him in (Mommy signed up late) was one that required 2 year olds to be potty trained. He had been asking about going potty, met all the requirements in the book and we decieded to go for it.
It was actually the worst day of our lives. I strongly suggest that if you deciede to do it, you do it alone not WITH your husband. We had extreme variation in our understanding of the intstructions. The end result was that our son sat on the potty chair, on a tarp, watching Wonder Pets for 6 hours straight...Are you aware that you can put a gallon of Juice (we measured) into a 22 month old and have NOTHING come out for hours? Who knew.
The next day we continued on wearing the big boy pants. On day three we were ready to give up, except that while I was at work, he told his nanny he wanted to sent his diapers to the Wonder Pets because he only wore big boy pants. (giving away the diapers was a suggestion from one of our friends) So...I came home from work and we had "given" away our diapers because we were such a big boy. We reached a new level of commitment.
Anyway the end result was about 2 months of wet pants several times a day (I'm suprised we are still allowed in serveral restaunts) and then we sent him to school with fingers crossed figuring they'd be senting him back. He's never had an accident in school. He just completed his first full year and he's three. Of all our friends, he's the only fully potty trained 3 year old (this is NOT a bragging right I would have been trying for if it hadn't been for the school).
We just conquered the poo-poo on the potty part (he used to just hold it an do in his pull up in the morning). The book claimed this would follow "naturally". Ha. I think this part might be easier for girls because our big poo-poo problem was going pee-pee on the floor when he tried (different equipment).
His best friend goes to a pre-school that potty trains them. if I had it to do over, I would have been standing in line the first week of Feb to get him into one of those schools in the fall.
Final Answer...it was difficult, it took longer than one day...but basically..my son is potty trained and has never had an accident as school so I guess it worked.
Good Luck...and remember...they don't leave for college wearing diapers so they will eventually potty train.
