for me, I didn't set any timetable for my daughter to quit. As she grew older, she didn't eat that much - 1 when she woke up, 1 before sleep in the afternoon & finally 1 before sleep at night. When she's about 18 mths., she can sleep without bf in the afternoon - just twice a day! Around her 27-28 mths., she suddenly hurt my nipples when bf. She couldn't control not to hurt them. & I felt so painful I couldn't feed her anymore. She cried 2 times - 1 in the morning & 1 at night. I let her see my nipples & told her how painful I felt if I let her bf. She seemed to understand & didn't ask anymore. She then quit! She just sometimes asked whether my nipples recovered or not, but not bf! This happened during SARS!
