probably a stupid question Re: cows milk

[2CheekyMonkeys]

so DD2 is having cows milk in a bottle now (at night) but most of the time is unpredictable in regards to how much she will take each night. my question is, can i re-heat her milk to use it again. it is already heated once (for the original feed) so i am thinking no.

thanks

I wouldn't think so because I think heating it once gives the right environment for bacteria to start breeding if you have it straight away it is okay, but if you cool it and then reheat it, bacteria has had a bit of chance to reproduce.

I could be really wrong, but that is how I understand it. Anyone else feel free to correct me if I am wrong
