I have a 9 month old who is on solids. He is nursed about every two hours during the day and every 4 hours at night. He seems to eat a lot when he is given solids and acts really hungry at these times. I was wondering if he was getting enough milk. This past weekend I had to travel and could not bring him with me so I used my medela pump. I tried to pump as frequently as he is fed, but I was only getting 1-2 ounces per side after 15 min of pumping. Could my supply have suddenly diminished? I also recently started menstruating again.
