Hi
Yes! to me the term EC sounded strange when I first heard it - then after a while (several years after actually) I realised that up until the advent of good disposables - most mothers used the technique of learning when their baby was likely to wee and/or poo and "held them out" in anticipation making appropriate noises as you described. I don't think we gave it a name - it was just part of bringing up children.
When I had my three children I found that if I got it right - then I saved a lot of washing
I used to take off the nappy before feeding, and pop him/her on a small potty immediately after - make pss-pss and grunt noises - (I agree that the position you hold them in helps quite a lot). In between feeds I kept checking the nappy and kept a potty (or bowl for very little babies)handy and could often catch a pee. It was amazing how soon they learned the routine, and would respond with making the appropriate sounds themselves as they used the potty certainly by 9 months. Mothers did this as a routine - we never had to force the child - but always showed how delighted we were after sucesses.
Another advantage of pottying was that babies rarely had nappy rash after the first 3 or 4 months, they spent more and more time without a nappy at all. We were always looking forward to the summer months when they could run about with just a Tshirt. Then by the time the cold weather came - we aimed to have them out of nappies altogether.
My two boys were clean and dry day and night by 14 mths - my daughter was during the day but not dry at night till she was nearly 4. I didn't like to tell people that she was not dry at night - I even thought there might be something wrong with her.
One night a friend gave me an incontinence pad that she had spare after her child had had surgery. Stephanie said she didn't like it - but I said she had to have it under her to save the bedsheet from getting wet. From that night on she was totally dry.
