I have been pumping once a day to get used to it and to try to start building a small stash for when I go back to work and also to have the occasional bottle for when DH or grandma watch DD. Yesterday I pumped 2 oz and today I pumped 1oz, both the bottles are currently in the fridge. Is it ok to combine the two bottles and feed them to DD? How long is breastmilk ok to be in the fridge before going bad? Thanks!
