Re: Starting EC from newborn stage?
We used a Glad 're-usable/disposable' 2 L container for a few months, and held our son over it. No special clothing, except we found T-shirts much easier than onesies (we cut off a few onesies). At night we used Motherease diapers with no cover, and put down about three layers of receiving blankets on our bed. That way I could tell when he was wet, but the bed sheets stayed dry.
I found EC'ing from birth quite rewarding, because they poop so often that almost every time you hold them over the potty, they go!
