1. Start a food journal. Yes it can be annoying, but it is a good way to make sure you are cutting out what you shouldn't be eating. After a few days of documenting everything you eat, it is easy to analyze what choices should be changed.
2. Breastfeeding is said to help shed the pounds, but don't eat less. To keep up the milk supply you will need approx. 2500 calories. Even if you are not breastfeeding, don't eat less. It is important to eat good small meals often. It is not good to starve yourself no matter what.
3. Start walking. It is difficult to take your baby to the gym, so start walking. Not only will your baby enjoy the outing and new things to look at, but the excercise is great for you.
4. Some gyms will let you take your baby to their daycare once your baby is 3 months old.
5. Eat good proteins to keep your body going. When I feel myself craving some sweets such as chocolate I grab a boiled egg and scarf it down. Not only does this take away the bad craving, but it lasts longer.
6. Give it time. Internally it takes the body about a year to recover from childbirth. Don't be discouraged if you are not satisfied with your outside appearance for a while. It takes time.
