hi! i'm a working mom and i've been pumping since my milk supply came in. my son is 5 1/2 month now and during the day he drinks from the bottle (breast milk) and when i pick him up, i nurse him. up until now, i'm usually able to pump enough for his one day feeding but now, my milk supply is decreasing and i have to take an extra 4 oz from my stock pile in the freezer. that stock pile is diminishing and i'm worried that i won't be able to bf him for long. i try pumping more at night but that doesn't seem to help. i'm thinking of supplementing with formula when my reserve in the freezer run out. i really don't want to give him formula even a little bit. what can i do?!
