I have a 35 weeker that is 5 weeks old, so just a few days past his due date now. I had been exclusively pumping until this week when baby learned how to latch with a shield (stupid thing. that was a dumb choice). 3 days later my supply has completely dropped. I am only getting 1ish oz per side every 3 hours and he eats more than that. I have some milk frozen but it has milk and soy in it and we have now eliminated that from my diet. What can I do, like now, to help my supply?
