The reason i did cc was because dd was such a clingy baby and such a frequent feeder (used it for food/comfort/going to sleep etc) that I knew i had to do something. Because she was b-fed to sleep, it meant she woke up several times a night because that was her sleep association. And because i wasn't weaning her any time soon,I decided cc was the best way to teach her to sleep by herself. I imagined that if i didn't do it, i would have night-time problems for many many months to come, and while that is very pessimistic, i believe it is probably true, judging by how often she breastfed up till being weaned, and also by how clingy she was, and also she would only nap during the day on me, never cracked the daytime naps!
gone totally off the topic here, sorry... i guess it ties in with the 2 yr old twins exhausting their mother. someone said earlier that she didn't need to wean them to get a night's sleep - very very true!
