There is no evidence to suggest that chubby babies become obese adults. In most cases, baby fat will disappear as your baby grows. Don’t worry if people comment on your baby’s plumpness.
And don’t worry either if your breastfed baby seems chubby during the first few months. It won’t last!
In fact, breastfeeding actually reduces the risk of obesity in children. Continue breastfeeding as long as you like.
Take the time to observe your baby. Learn to recognize her needs (often emotional) and fulfill them with other means than food. Try not to reward or punish your baby with food.
