Laura, don't want to scare you now. I have a 7 year age gap between DS #2 and DS #3 I bf #2 til he was 9 months old and still could get some milk out if I squeeze uptil the time I fell pg with the next baby. I must say though, I don't remember getting the letdown sensation after he was weaned though.

I fed DS #3 til he was 20 months and still had milk when I fell pg with Tehya too. Although that was only 6 months later.
