Re: My milk output drops drastically at my 11pm pumping.
It is normal for moms to experience a bit of a supply dip in the evenings. Prolactin levels tend to peak in the night and then drop throughout the day, reaching their lowest level in the late afternoon-evening. The only way to change this pattern is by either allowing the baby or babies to nurse as much as possible, or to mimic that constant nursing with the pump, i.e. Pump your heart out during that period. The increased demand will train your body to increase supply.
Basically, I'm saying that you probably need to add in some pumping sessions, particularly when your yield is lowest.
