I also have a sample of one, and we broke many of the rules. That
said, I didn't break the basic food handling rules, so I never added
warm milk to cold, or warm to frozen, just as I wouldn't with any
food. Still I rarely combined milk that wasn't cold, because I always
expressed more than one feed at a time, I would take one feed out and
then combine the remainder to make another. I also froze in bags, so
couldn't really add to them, I combined the amounts in the fridge
regularly though. I never threw milk out if I could avoid it, then
again, I had some that made it well over 12 months in the freezer and
it went out because Michael didn't like thawed milk. I actually gave
up on freezing for a while, as it was a waste of freezer space. I
also changed a few definitions, one feed lasted until the bottle was
empty so I never threw out the last of the milk in the bottle. My boy
never got sick, however, he was healthy to start with.
On the shaking, I read an article by Lara (can't remember her surname,
but she's on lactnet) that debunked the theory, I can copy and paste
it for you, but I can't forward the original email as its in the web
archives for another online group. Good think too, as we carted the
milk around in a red insulated bag and it got thrown, and dropped and
all manner of hard usage, especially once Michael was older and knew
what was going on. The milk was always perfect, he grew really well,
so I don't worry about shaking. Actually it doesn't make a lot of
sense to not shake milk, its the only way to get the fat off the
sides. I also stopped warming my milk and he drank it at the temp it
came out of the bag.
Freezing recommendations, not sure of the science, but in Australia
the NHMRC recommends that it be stored for 2 weeks in one of those old
freezers inside the fridge, for 3 months in a freezer section of
fridge with a separate door, and 6-12 months in a deep freezer (-18C
or lower). So it depends on how cold your storage place is.
Normal food handling recommends that milk be stored at the back,
because if you store it in the door it gets exposed to hotter air
everytime the door opens, I never worried about that, it really
doesn't sound reasonable because the door is only open for moments,
its not like you hold the fridge door open for 30 minutes trying to
find things, or do you :)
I suspect that there isn't a lot of science for many of these things,
most are based on regular food handling and some on passing statements.
