Thankfully, the success has continued. Elijah has stayed dry with only one accident and has gone in the toilet two times. One of those times he was standing up like a real big boy. That made him feel so cool and he continued to talk about it afterwards. "I stand on da stool and pee in da potty, like a dada!".
After browsing through the official Potty Training Boot Camp book last night, I decided to go ahead with some sort of reward. The book suggests to give a reward both when the child goes in the toilet but also if they are dry when the timer rings. Elijah has been able to enjoy numerous little "gummies" (Annie's Organic fruit snacks, ha!) throughout the day and we are all very happy.
I have just started a medium sized load of laundry (another success!) and am off to bed myself to rest up for the afternoon/evening.
