For me...that's really a fairly easy question to answer, I had difficulty producing enough milk for my son. I've learned in hind-sight that there were a few things I should have done differently as far as the equipment I used to express/store milk for my son....but that's pretty much it. I simply had difficulty. Had I been able to, I would have continued to breast feed him probably until around 1yr.
I weaned him off of formula though shortly around 1-year anyway...around the time he started showing an interest in foods. At 2.5 my son will now eat almost anything I put in front of him (looooves chinese food!) and would much prefer fruit, yogurt or cheese...and oh yeah, green beans over any candy out there. :-) Fortunately my little guy has no allergies for me to deal with either.
As Karen said though....my son kind of told me when he was ready to move on so-to-speak. I've known some women to go much longer than others, but for me....I just went with what felt right.
