I am nursing my 6 week old ds on-demand & i occasionally pump & my dh gives my ds a bottle so i can get some extra sleep. when i pump in place of bf, i notice that i don't fill back up for the next feeding. my breasts are saggy & the baby doesn't get enough. it's like the pump fully empties me-so much more than the baby does. i'm wondering....should i not pump until i'm fully empty or maybe i'm turning the pump up too strong???? i turn it all the way up & it only takes me like 3-5 minutes to fully empty my breasts. during the night last night, i pumped 5 oz (my ds only drinks 3-4 oz) but then i was still empty at the first feeding this morning-when i'm usually the fullest!!! i had this same problem with my dd, but also had other issues with milk supply, so i was hoping this time would be different. has anyone else experienced this with the pump??
