Suddenly cant keep up

nattyk

I'm hoping someone here can help.  I EP, and usually produce about 30 oz per day.  DS eats between 25 and 30 oz per day.  I used to pump for the next day, but for the last week or 2, I've been having trouble keeping up with him.  I'm not exactly sure why, as I'm pumping the same amount and he's eating the same amount.  I had to dip into my freezer stash 1 day, and the stash really isnt that big to begin with (about 60 oz). 

Any ideas as to what might be going on?  I havent made any changes to diet or exercise, and I'm not on birth control.  I havent felt like this since I first started pumping at about 3-4 weeks, and have never had to dip into my stash before the other day.  I realize that I've been very lucky with my supply, and maybe I'm just overreacting, but it stresses me out to have exactly enough for him (not counting the freezer).
