I have a 3 week old son and the last couple days I have been concerned that he isn’t getting enough milk. I breast feed and pump, so I have a few breast milk bottles stashed away. The last couple days he has fed for over an hour on the breast and then will be happy for a couple mins and then start rooting and crying like he is hungry so I will give him a pumped bottle and then he will be happy. Am I not producing enough? The last couple days I have barely been able to get anything pumping. I used to get 4-6 oz combined and today I got less then an ounce. I haven’t changed anything. Any ideas?
