How long are you supposed to pump for? I usually pump 15 minutes the most because I stop getting milk around 10 mins. My let down (1.5oz) usually finishes around 5 mins then the rest is just drops. Then around 10-12 mins nothing else comes out? Am I doing something wrong? Sometimes I pump for the 20-25 mins minutes but nothing comes out after 15 minutes of pumping. I usually get 3-4oz every 3-4 hours and if I wait longer than the 3-4 hours I can get up 6-8 ounces. (I know I’m not supposed to but life happens with a fussy baby)
