If I was going to use the milk the same day, I might not worry about mixing warm/cold as much, but definitely wouldn't combine if I planned on freezing or storing in the fridge for a few days. Agree with the raising the temp of the milk encouraging bacteria growth.

I figure if it's going to go in the fridge anyway, why not have it go in the fridge in an almost full bottle of cold milk, vs a 1 or 2 oz bottle only to mix in a couple hours? I hate leaving behind that ring of fat in the bottle when mixing.

Not sure how true that is as I've never looked for the research, but I've never had a problem combining. snowjewelz on "Do you always follow the mixing "like with like" pumping rule?" https://boards.hellobee.com/topic/do-you-always-follow-the-mixing-like-with-like-pumping-rule#post-2544207 Mon, 09 May 2016 08:42:50 +0000 snowjewelz 2544207@https://boards.hellobee.com/ I mostly followed it, but it's so hard to keep all the rules together sometimes!

I think you don't want to warm the cooled milk for it to grow bacteria. If I was just adding 1oz to a pre bottle of like 8oz I figured it would be fine. travellingbee on "Do you always follow the mixing "like with like" pumping rule?" https://boards.hellobee.com/topic/do-you-always-follow-the-mixing-like-with-like-pumping-rule#post-2543776 Sat, 07 May 2016 20:27:48 +0000 travellingbee 2543776@https://boards.hellobee.com/ Always followed that particular rule. catlady on "Do you always follow the mixing "like with like" pumping rule?" https://boards.hellobee.com/topic/do-you-always-follow-the-mixing-like-with-like-pumping-rule#post-2543775 Sat, 07 May 2016 20:24:15 +0000 catlady 2543775@https://boards.hellobee.com/ I didn't worry about it. I would often pump directly into bottles already containing refrigerated milk from previous sessions that day. I would put them right back into the fridge afterwards though. I wouldn't have left them out and then re-mixed. As it is, I had to scald the milk once I got home anyway, so I figured bacteria would be killed at that point if there was any. mrs.shinerbock on "Do you always follow the mixing "like with like" pumping rule?" https://boards.hellobee.com/topic/do-you-always-follow-the-mixing-like-with-like-pumping-rule#post-2543758 Sat, 07 May 2016 19:44:07 +0000 mrs.shinerbock 2543758@https://boards.hellobee.com/ I never follow it, but I think the reason they say it is because of bacteria growth. The warm milk raises the temperature of all the milk and encourages bacteria growth. Same reason you shouldn't leave a juice bottle out after you've drunk out of it. kiddosc on "Do you always follow the mixing "like with like" pumping rule?" https://boards.hellobee.com/topic/do-you-always-follow-the-mixing-like-with-like-pumping-rule#post-2543756 Sat, 07 May 2016 19:32:44 +0000 kiddosc 2543756@https://boards.hellobee.com/ Never followed it. I would sometimes pump directly into the same bottles with milk from earlier in the day at work. artsyfartsy on "Do you always follow the mixing "like with like" pumping rule?" https://boards.hellobee.com/topic/do-you-always-follow-the-mixing-like-with-like-pumping-rule#post-2543740 Sat, 07 May 2016 19:01:35 +0000 artsyfartsy 2543740@https://boards.hellobee.com/ I always followed it. I refrigerated my milk at work and mixed them to make full bottles at the end of the day when it was all cold. I wasn't anal about it, it just worked out that way.

I think the point of the rule is to make sure that the oldest milk doesn't end up being at too warm a storage temp for too long. I pump pretty small amounts, and I store in a very cold cooler bag. I combine until I have enough for a a bottle. It cools quickly enough that I've never been concerned. winniebee on "Do you always follow the mixing "like with like" pumping rule?" https://boards.hellobee.com/topic/do-you-always-follow-the-mixing-like-with-like-pumping-rule#post-2543724 Sat, 07 May 2016 18:13:08 +0000 winniebee 2543724@https://boards.hellobee.com/ I kinda did? But I often would cool fresh milk and mix it with defrosted or heat defrosted and mix with fresh.

DesertDreams88 on "Do you always follow the mixing "like with like" pumping rule?" https://boards.hellobee.com/topic/do-you-always-follow-the-mixing-like-with-like-pumping-rule#post-2543717 Sat, 07 May 2016 17:30:51 +0000 DesertDreams88 2543717@https://boards.hellobee.com/ How often do you follow the mixing "like with like" rule for pumped milk, as in, you can mix two bottles of warm/freshly-pumped milk, or two bottles of cold milk, but you can't mix warm and cold? I think this is a bit of a silly rule and can't find a good explanation for it. I follow it about 80% of the time but sometimes it's just more convenient to mix, rather than wait, especially if it's just an oz or so. I hate storing bottles with just 1oz to chill before mixing! I'm probably not going to change my ways, but just curious!
