Tricia:
Seems like there were some previous posts or maybe on the other forums that mention shaking things up a bit...adding interval cardio work, or changing the type of cardio workouts you are doing. Altho, as you said, probably it is consistency that is needed. Also, I have heard that diet is 80 percent of results, or whatever, but that appears to be debatable. Perhaps consistency really is the issue with you.
I do think our bodies want to hang on to fat to breastfeed...but unless someone was ultra lean before, it seems like the average fit woman (not someone with the ultra low body fats) would have enough fat to make breastmilk without holding onto another 10 lbs on top of it all! However Cathe mentions in her before and after baby picture section that she held onto extra lbs til she weaned...but perhaps her body fat is so low that it was necessary for her..mine isn't. Or perhaps it was just a time factor...seems like she may have weaned before 8 months, unlike yourself (not sure).
My baby is ony 2 months, but as soon as he is sleeping thru the nite, I am going to try for an early am workouts before he wakes up, along with his 2 brothers. Finding time to workout is the biggest challenge to a post partum body!!!
