American Academy of Pediatrician suggests strictly beast feeding for first 6 months and to continue at least for the first year. World Healtsh Organization suggests breast feeding for the first two years. If you really enjoying it there is no reason why you should. I have a 2 year old that I am still breasting. But I must say it would be so much easier to wean at 18 months that it and would be at 24 months. I know from my son that he now knows what he wants and how to go right for the breast; he serves him self without requiring any help. Which makes the weaning very hard
