Because breastfeeding is an effective measure to prevent obesity. But there are some exclusively breastfed baby overweight occurs, the reasons are as follows: 1, genetic factors: birth is a huge child, there is no genetic history of obesity in the family, whether the mother suffers from diabetes during pregnancy; 2, overfeeding: because of the baby's dependence on the nipple, so many babies will contain the mother nipple to sleep, a crying mother will be comforted with breast milk, so too much to eat resulting in overweight babies. Long-term overfeeding will lead to the baby appetite is very large, intake of nutrients, coupled with small months of baby activity itself is very small, so overweight phenomenon will be generated; 3, breastfeeding when adding complementary foods too early, too much: overweight is very unfavorable to the baby's health, appropriate control of the baby's diet, in order to facilitate the growth of the baby.

2. Early addition of complementary foods: some parents add complementary foods to the baby's time is relatively early in the 4 months when the baby to breastfeed, and worry about the baby is not enough to eat, but also to the baby to add complementary foods, early addition of complementary foods for babies, the impact is very great, the complementary foods inside some of the elements is also the cause of the baby fat too fast.

3. Excess milk: In order to have enough healthy milk, the mother's diet will choose nutritious soup, which leads to the mother's milk excess nutrients. After the baby ate the milk, the excess nutrients are also converted into excess fat accumulation in the body, which is also the cause of the baby too obese.
