My baby is now 2 months old and she'll start day care at the end of this month. I thawed a milk bag (more than 7 oz of milk in a Lansiloh storage bag, dated 12-01-2010) and wanted to bottle feed her but she is rejecting this milk. Why? How can I have her get used to the taste since I have a stash of these bags? Can I mix thaw and fresh milk? If so, how many oz should be thaw and how much fresh? Can you really mix two separate milk temperature (thaw milk - cold, fresh expressed milk - warm)? Day care only allows to store milk already in a bottle. For feeding schedule, should they give her one feeding session, fresh, then next thawed milk? Do I have to smell the thawed out milk first? How can I know if this a "bad" bag (does milk have a smell? different color?)? Is storing more than 6oz in one bag bad? I figured one bag can be two feedings (I guess I'm trying to save a bag instead of using two bags (3oz each)).
