Is it true that formula fed babies are more likely to become obese children/adults than breastfed ones?

As what Idza has mentioned, there are a number of factors at play that may have contributed to the link between formula fed babies and higher rate of obesity. A common reason is that when a baby is breastfeeding, he/she responds to the signals sends by their body to indicate that they are full. They will naturally stop suckling once they are full. A bottle-fed baby, on the other land, may be encouraged to finish their bottle instead of responding to the satiety cue. In other words, there is a chance that a bottle-fed baby may overeat. However, it is possible to help your baby develop healthy eating habits by being sensitive to his/her feeding cues (and not based on a feeding schedule). Infants have small stomachs and would like have frequent feedings but with smaller amount. There is no need for babies to finish the entire bottle of milk he/she was given. Once they seemed disinterested, it is a cue to take the bottle away. There are also times where he/she is crying for comfort and not food. Hence, don’t be too quick to offer him/her the bottle, trying soothing by rocking or other means of relaxation first.
