We did late and lazy EC with DS. We started around 7 months and really just for #2. By 13 months he would tell us he had to go potty and walk to the bathroom. He is 2 now and hasn't pooped in his diaper in a very long time. We are still working on pee. With the new baby I am thinking of starting earlier. Like 4 months or so. It ended up be a lot easier than I thought it would be.
