Combining cold BM

outrunthemoon

So I used to put pumped milk right in the freezer. Now I keep some in the fridge for a quick grab if needed. I try to pump once a day just to keep a small stash. Some days I get 4 oz, others barely an ounce.

Is it okay to combine the BM that is in the fridge from different days? If I don't use the milk after a few days I put it in the freezer but I don't want to freeze such small portions.
