My M was not stable (35-45 days) when I continued to feed my daughter when she was 10 -24 months old. After I stopped bf my daughter when she was 2, my M becomes stable (28-30 days, same as before).
Now, I feel more comfort to bf my baby. Before that, I am so sad when I heard the bad news (just the wrong info.) from the doctor. I really want to continue to bf my baby until 1 year old.
keep on bf your baby regardless your M comes or not. your milk supply depends on your bb's needs for mama milk - when baby starts solid food and demands for less milk, your milk supply will be reduced automatically. your M has nothing to do on your milk supply.
