My milk is well balanced with LO these days, but I'm starting to worry about my very measly freezer stash. I've only ever pumped recreationally, and only had 8 or so bags even in my pumping prime. But now I'm down to only 5 bags and lately I haven't been able to replace what gets used because LO eats much more than I can pump.
Does anyone have experience with using formula very sporadically, only while LO is with a babysitter? I'm talking maybe twice a month. Is this a thing?
