so I don't know when you had your baby but it does take a little time to lose it all...don't get too concerned. Focus on healthy eating. If you were a good weight before baby than get back into your old eating and exercise habits again. Even when your weight come off the post baby body needs some special toning and time to get back into shape...you were pulled all different directions for quite some time!
mostly its will power. You have to be ready and committed to make it happen
