Well I havent had a baby or anything, but just in general you should just eat a balanced diet. Not eating anything or eating just once a day is not good. You need to eat small meals several times a day to keep up your metabolism. If you keep your metabolism up then you lose weight easier. Also, excercise! It doesnt really matter what you do...Just do something!
Right now, I am doing weight watchers! Its so easy! I'm not going to the meetings or anything, I just know the diet! I can tell you about it if you want me to! You'll lose that 30 pounds...Give it time!
