How long should one breastfeed ?

Personally, I don't think there is a right or wrong answer to this. The normal weaning period happened between 2 to 5 years old. It is a question that you should ask yourself on how comfortable you are in doing extended breastfeeding. My firstborn self weaned at 28 months when I was pregnant with my second child but continued to drink my milk after I gave birth up to now.
