I personally would encourage mums to breastfeed their babies for longer.. I did my part for 26 months. Have an amazing bonding with my baby. Mothers feeding helps kids gain immunity. . protects them from frequent cold . Fatty acids produced from BM helps in Brain Development. After a vaccination it's only a mom's feed that soothes the baby. Helps baby gain weight!! There are many more but nothing BEST AS BM for until 6 months atleast!!
