Had to add to this as issue close to my heart, had c- section in January an elective one at that so I was sort of prepared..
However, I was slightly naive, in that being a dancer for 20+ years I thought I would heal very quickly and be back doing my sit ups etc. Ha ha ha, I am now nearly 5 months on and still looking like i'm 3 months pg.
I still cant do alot of sit ups as the area around the scar gets sore, ~i made the mistake of trying to do loads soon after only for my scar to get to very very sore and I got a lump where the scar tissue is on the right hand side.
Never underestimate how serious having a c- section is, I was very naive and didn't appreciate what it would do to my body. have slipped into slight PND as a result as looking at my terrible overhang brings tears to my eyes when I had a figure to die for.
I agree with witchandchips, walking is an excellent way to get the tummy back in shape. If you get time to do this that is, I have found it really difficult to do loads of walking with a demanding dp wanting the house spick n span. hmmm, nice when I have had major surgery to have his baby, fecking men do my nut in.
The moral after my huge essay (sorry about that btw) is take care please listen to your body and if its starts to hurt stop. Accept it will take time as I have done..
