I stopped when James was 17 mths old and he is now 33 mths old and I still get a little bit of colostrom from one nipple in the shower sometimes when I try!!! Human body is pretty incredbile.

BR - There are others that are more knowledgeable but I would think that yes if you wanted to pump say once or twice a day to give him EBM you could increase your supply, esp if you are still leaking.
