Re: EC ?
You can definately do poos only. IF you can catch them with great regularity. I always have the most trouble with them. We use the toilet ASL sign and when it clicks in the brain that the sign and action go together, we're home free. No more scary trips to the store waiting for that BM. We also use a low pitched hmmm sound. It's easy for babes to do along with you when they're pooing.
For me, pees have been easier. They're easy to time. You can always give the babe the opportunity to go when they wake and about 15-20 min after the nurse. Even catching 3 or 4 pees a day makes a huge difference in the amount of laundry done.
