Last time an old doctor told me that if I decided to breastfeed my baby longer than two years it will substantially increase his immune system because it is still created at this age. This was naturally for human to breastfeed until the mum had the milk, even after the child was five. We changed this practice in XIX century because artificial nourishment occurred. The practice of giving children different food than mum’s milk was developed by nutrients producers. Breastfeeding after the child is two years old influences positively on it’s relation with mother. What is your opinion on this matter? Have you ever met mothers breastfeeding the children at that age.
