Hi Jackie,
I'm not sure about the aids, but you may want to do a search on the FitMom Forum. This is usually a source of trouble for pregnant women and new moms.  I know Sheila gave an excellent and detailed break-down as well as I series of exercises to do, progressively harder.  Now, that was on the old forum, but I imagine you may still be able to find it if you do a search.  Hope that helps, I know this can be an annoying problem!
