Actually, I have seen mothers breastfeed more than 5 years It is completely up to mom and baby to continue the journey. Exclusive breastfeeding till 6 months, and breastfeeding till 2 years seems to be the recommendation by WHO.
Some mommies have gone beyond 2 years. As long as you keep nursing, there should be supply. WHO recommends breastfeeding exclusively until baby's 6months old. Thereafter breast milk can compliment solids
Thanx dear
