This is fine. 2-3 oz of milk from both breasts combined is normal output, and is excellent if you're doing it right after feeding the baby. Don't feel like you must feel full in order to pump, though.
1. Currently i am pumping when i get up for the mid-night feeding, that is the only time i feel full. after feeding my baby i pump for about 15 mins (one breast at a time) and get anywhere between 2 to 3oz of milk.
2. Is it okay to pump one breast at a time?
Yes, this is fine. Not all women experience the letdown sensation. I nursed 2 babies for 3 years apiece, and never felt a letdown.
3. I dont feel the let-down, neither during pumping nor during breast feeding. is this okay?
Totally normal. Milk typically comes in fits and starts- nothing, then drops, then a letdown, then slower flow again, then nothing- and if you pump long enough, maybe a second letdown.
4. When pumping after the initial 2 mins (which is let-down reflex) the milk comes for 3-4 mins more and then it stops. is that normal? is the phalange size a problem?
Normal. People aren't perfectly symmetrical and there are bound to be differences up between breasts. Usually one breast has better supply than the other, and you can definitely have one breast that is easier to pump from than the other.
5. I, then massage the breast to get milk spray going again. This works good with my right breast but from the left i cant get more milk after massaging also.
1. Pumping should be comfortable. Your nipple should not rub against the sides of the collection tube.
6. how do i know which size is best fit for me?
2. You should not feel a loss of suction while you're pumping.
