Re: Sterilization and storage questions
If you have a healthy, full-term infant (or older), then there is no need to sterilize anything. I sterilized my pump parts once every couple of months, but even that wasn't strictly necessary. Most people sterilize the first time they open new bottles from the box; I did about half of mine.
I think most people who freeze in bags then defrost/warm in bag, and pour into a bottle for feeding.
If you're transporting bottles full of milk, I would keep the screw cap on the bottle - pretty much any bottle that's sold has both the screw cap and the nipple cap, right? If you have a specific need for sterilized bottles, let us know and we can help you brainstorm.
Yes, you can freeze milk from fridge after 3 days. BUt if you know you're going to freeze it anyway, it's better to do it immediately, since the longer it's stored, the more it breaks down.
I would think that bottles etc would stay sterile as long as you keep them in a sterile environment ... which is basically nowhere in most houses Again, let us know if you have a specific need for sterilization and we can help you brainstorm.
