I have breastfed all 3 of my children. My daughter for 21 months, my son for 19 months and my youngest son is still nursing at 23 months. I weaned my other 2 and I am thinking if my youngest doesn't self wean by this spring that I will have to help him.
The American Academy of Pediatrics recommends breastfeeding through at least the first year. After that breastfeeding can continue as long as mutually desired.
The World Health Organization recommends breastfeeding for at least the first 2 years.
Also, the American Academy of Pediatrics recommends no solids (cereal included) until at least 4 months (preferably 6 months), and the baby has doubled his/her birthweight. Many people say that you must be starving your baby because he or she nurses so much those first few months, but no solids are needed. Breastmilk is the perfect food, and the calorie content will change to meet your baby's needs. I would recommend nothing but breastmilk until your baby is at least 4 months. If you start solids too early your baby could be at risk for food allergies, and your milk supply could go down. Your baby would then be missing important nutrients and antibodies that are in your milk. Just my 2 cents, but this is a topic I have lots of experience in. Take care.
