I talked about using EC with Violet in this post when she was about 7 months old. Since then, we have had a long road, and we have had very few poopy diapers. In fact, even when Violet got a horrible stomach flu (this has happened twice now) and had really bad diarrhea, she still didn't poop in diapers. That is control. The peeing... well, that's another story.
So Violet has been almost exclusively pooping in the toilet since she was 3 months old, and peeing in the toilet as long too- just not exclusively. At 26 months, she still pees in her diapers. We are working on it, but don't feel a huge urge to pressure her. We do a lot of naked time at home (mostly because she doesn't want to wear clothes, not because of some structured naked time). We got her cute panties that are not for peeing in, but accidents still happen in them (although she is more prone to tell us she has to pee if she's wearing panties). We try not to make a big deal of accidents, and we try to stay positive. Anyway, that's where we're at with her.
If nothing else, we've giving her a comfort with the toilet, which many children her age don't have. Many parents I know face the issue of a child afraid of or confused by the potty. By offering the option without pressure early on, you solidify that connection between our bodily waste and the toilet.
At 6 weeks, my new baby Desmond is making leaps and bounds. He's gone pee over the toilet about 5-6 times now, and pooped about 3 times. I'm using the same method I used with Violet; I just hold him over the toilet during his diaper change. I've also taken him in just after a feeding and had good luck that way too. Unlike Violet, who screamed if you held her over the toilet (which is why we gave up until 3 months when she was more comfortable with it), Desmond is content to be held over the toilet, and looks up at me happily while we wait for nature to take its course. We will see how he progresses, but so far I'm optimistic.
