Some like it hot, some like it cold

Sam has a very definitive taste when it comes to bottles. He will never take frozen milk that's been thawed in the fridge. Nor will he take frozen milk that's been rewarmed a second time. [update: since correcting the lipase issue and freezing immediately after expressing, Sam will take a bottle that's been rewarmed twice! So he doesn't have to finish his bottle in one shot anymore.] Now we know it's probably because of my excess lipase issue. He also likes his bottles really warm, even warmer than the temperature of milk when nursing, which is presumably 98.6 degrees or so. I wonder if that somehow masks the metallic/soapy taste caused by the lipase.

So I try to freeze my milk in two categories: full bottles like 4-5 ounces, and toppers of 1-3 ounces. This way, if I even think Sam might not want a full bottle, I try to have him take a smaller bag's worth so we don't waste so much milk. He will not take the leftovers a second time, only on random occasions, but I can't rely on that.

I don't have his bottle-taking habits down to a science because I'm not the one who actually gives him bottles. He wouldn't take one from - the last time we tried was when he was 2 months old, so who knows. Maybe he would drink from a bottle if I administered it. But there's really no need for me to give him one if I could nurse him. Sam only gets bottles at the babysitter, so she's the expert!
