V.R.
I haven't read any of the responses, but honestly, I never lost my tummy (had a c-section at age 35) & I weighed exactly what I weighed when I left the hospital...2 years LATER. I breastfed for 15 months - no changes. I changed my diet. No changes. That 15 pounds & a "preggie" looking tummy stuck on me for years.
The only thing that reduced my tummy as well as helped me get back to my pre-pregnancy weight was joining a gym. Walked on a treadmill, did the eliptical, worked with weights. 6 months later I could not believe the difference.
I am now 4 mths pregnant, still working out as much as I can muster & am hopeful that I won't be stuck in the "baby body" rut for years after this baby simply by keeping up my exercise & watching my diet. I certainly still had a ways to go & was nowhere near having a slim & trim waistline, but I knew that, for me, exercise was more effective than anything else.
Good luck!
