When I got home from the hospital, I was only about 7lbs heavier than my previous pregnancy weight. However, since then, I seem to have been piling on the pounds! It must be all the catch up with friends that include cake. Baby is 3 months. Realistically, when should I start a diet? I want to do weight watchers again. I am currently breastfeeding. I'm embarrassed that I'm gaining more weight now than when I was pregnant!
