Re: State regulations not up to par :(
I would send just enough fresh milk to cover the baby's intake that day, and send some additional frozen milk in case the fresh isn't enough. I think you can expect an adjustment period in the first few weeks as you figure out what your baby generally takes at daycare. If that means you're arriving at daycare to find a whole bottle untouched, I think you should take it "for the ride home" and feel free to send it the next day. I doubt anyone will ask you if it's the same bottle you took home last night.
1) Fresh breast milk is supposed to be okay in the fridge for 3-5 days; in Indiana, licensed day care providers must use it within 48 hours. My options are to bring home any unopened bottles and freeze the milk, or lie to the day care provider about when it was expressed.
I'd contact the state regulators- you'd be surprised how much impact a single letter can make! Government regulators generally get very, very little input from the public. You could even get your local La Leche League involved- maybe the ladies there would want to send letters, as well.
2) Even though research shows that an unfinished bottle can be refrigerated and safely given at the next feeding, state regulations for day care providers say unfinished amounts must be discarded. My plan was to send 3 oz. bottles, but now I'm going to have to send no more than 2 oz. servings, which means sending like 7 bottles (5 - 2 oz. and 2 - 1 oz. "top off" bottles).
I definitely would send the 2 oz bottles, and call that an unlocked-for benefit of the dumb regulation. Small bottles mean less chance that the daycare will overfeed your baby, because they will be forced to pause the feeding to reach for another bottle- and that gives your baby a chance to decide whether or not he's still hungry. A couple extra bottles to wash is a small price to pay for a more appropriate feeding style.
