I put my warm bottles in the fridge, when they're all done in the warmer I put them in the bags and straight into the freezer.
If you do decide to start your LO on cereal or a fruit/veg puree, your DH can mix the unscalded milk with that and essentially spoon feed her the milk. Their little bellies fill up so fast you'll be surprised, seems like when it's milk though they'll just gorge themselves of course ;-)
Good luck to you, let us know how it goes! Or if you have more questions before then.
