Anyone can tell me how to slim down? Till now lo is 8 months old and I still look like as if I am pregnant 2-3 months.

Are you breastfeeding your baby? If you are, just to replace empty calories food with real food like vegetable and oat, proteins instead of carbohydrates. Also drink enough water; dehydration will give your body false information that it is hungry. I did that and lose my weight within first 3 months.
