Yes! Various studies are proving that breastfed babies are more attached to their mothers as compared to formula-fed babies. This is because the close interaction of the baby with the mother helps to bond more affectionately. The baby can have a feeling of being secure, and this is conducive to the development of the baby's emotional personality. But it also includes the baby's innate personality behavior and the environment in which he is being nurtured. Breastfeeding is just a minor factor.
