breastmilk in bottles (how long good)

Babymamawithdrama

ok, normally i pump into my medela bottles and store in the fridge or transfer to the bags, but now that I am back at work I am debating pouring from the medela bottles directly into the bottles for the following day for daycare (we have plenty of bottles).  Is there any harm storing them with a bottle (with nipple and bottle cap) in the fridge for second day (i.e. pumped milk from monday will be eaten on wednesday)?
