A little background before my question. I am a first time Mom to a 14 week old little guy. I've been breast feeding from the beginning. I started going back to work in December and have been slowly transitioning over the past 2 months from 2- 4 hour days/week to full time (5- 8 hour days/week). Right now I'm at 4 ~ 7-8 hour days but will back to regular schedule in the next couple weeks.
I've been blessed as little Ethan started mostly sleeping 7-9 hours at night at around 2.5 months. When he wakes up (or I wake up because I'm so engorged) he doesn't drain my breasts at the first feeding (I'm guessing he takes about 1/3 to 1/2 of what I have). I've been pumping the rest in the morning and usually get 6-9 oz. On days that I work I nurse him (while he stays asleep but it seems to work) pump then out the door. When I work a full day I usually pump twice and come home with 8-12oz (more earlier in the week usually). Dad's taking care of him while I'm at work. He tends to take 6-7 oz while I'm gone. My gut tells me that's fine as he tends to catch up by nursing more when I'm home before he goes to bed and he is chunky, active, diapers look good, etc.
Now to the questions. I have quite a bit of frozen milk. In addition to the morning pumpings, which go straight to the freezer on the weekend, at the end of the week I've usually froze about 20 oz more. My husband jokes about finding the veggies in the breast milk section of the freezer, but seriously, I'll be out of space soon. I've heard that nursing peaks between 4 and 6 months, but I'm wondering if I should back up on my storage capabilities and try to pump less but I don't want my supply to drop and not have enough in the future. Should I consider donating some of it? Any suggestions would be appreciated!
