Help! I'm struggling with the amount I am pumping. I pump three times at work and then exclusively breastfeed 4 month old DS in the evening. We even cosleep most of the time and he will eat off and on during this time. If he goes to sleep in his crib for the first few hours of the night, then I will squeeze in a pumping session. Do I need to try to pump more in the evening? At first I thought the amount was decreasing because my period came back but I'm still struggling to get 3 ounces per session at work. This isn't enough to get him through daycare, and I'm having to dig into my freezer supply. Any advice would be appreciated. Thanks.
