I wrote earlier how my daughter started elimination communication with my grandson around his first birthday. Once my grandson saw that he peed in the potty, he HAD to every time he sat on the potty. He is very motivated and loves seeing the outcome...pee in the potty. My daughter puts him in big boy underwear during the day. At nap and bedtime he wears a diaper(he wakes up dry, but needs to sit on the potty soon after waking or else he'll have a wet diaper). She also puts him in a diaper when they leave the house.
At 17 months old he was having around 1-2 accidents(we really dislike to use this word) every few days. Now, at 18 months old he tells us when he needs to poop. Pee on the other hand has been a little more work. Once he realizes he needs to go...he needs to go NOW. So at home 95 % of the time he makes it, but if he is outside it becomes harder.
Today was his first official trip (besides the park) in big boy underwear. We went to the mall to pick up some shoes for him. Before we left my daughter put him on the potty. About 30 minutes later we arrived at the mall and put him straight to the potty. Before leaving we asked him if he needed to go and he said no so off we went. He did really well, and stayed dry the whole time.
My daughter was very hesitant to begin taking him out in regular underwear, but after the success today she will definitely be taking him out in underwear from now and on.
I will update next week on his progress.
