I breastfed my daughter until she weaned herself at around 10 months. She took to biting me for some weird reason and I would pull away and say no. She would cry. After two or three times she just decided not to even try any more. We switched to a glass. I chose breast feeding because it's always there, no dishes to do, always the correct temperature and it made me feel like a true Earth mother. Also provided early immunity. But every mother has to decide what is best for her and her child.
