THat sounds about right to me. Bottom line is that pregnancy changes your body and it will never be the same: abs split, hips widen, feet get bigger (had to throw out lots of fancy pairs of shoes and even my favourite worn-in hiking boots), chest gets flatter (in my lucky little case, not!!!) and yes, there is thickening at the waist (bye bye 24 inches!).
I have managed to get definition in my core region and strength through working out with Cathe but as slim as I am, I will have loose skin there forever since I am not a nip and tuck fan and I have an athletic build, not a curvy one that indents a lot at the waist for definition, ah well.
So, yes, the body will never be the same again, but the question is do you really want it to be? Personally, I don't want to be a nubile 20 year old, body on display, read by all as a sex object...I don't identify with Shakira or Brittany, and I will take this body with its looser abdominal skin because it is way stronger than the one I had in my twenties, it gave me two fabulously healthy and fun-filled girls who have totally changed my life around for the better, and I am finally getting a sense that this body has its own unique shape and I need to give up the idea of making into something it will never be because that is akin to torture.
Get strong, build the best shape you can in a reasonable, not obsessed way, give yourself at least 6 months of consistent ab and core work both traditional (try MIS) and pilates orientated (see Cardio & weights and the PUB) and that's all you need to ask of yourself, right!?!?!
