DD's night feeds are currently EBM- two reasons 1) she is a slow feeder and night feeds could take 3 hours with the nappy change, feed, top up, pumping settling back to sleep (she has top ups due to slow weight gain). 2) she has knackered my nips at mo and is crap at latching properly at night when she is tired and I am too tired to sort it! This way saves loads of time and me nips!
Anyhow pumping yields about 90ml but as she has gone 4hours I like to give her 120ml so I make sure I have 30ml in fridge beforehand. Do you think it is okay to add this straight to the ebm? I know it's not advisable to have milk at diff temps in terms of microbes but this is going to be hitting the acid in dd's tum in minutes so bugs wouldn't have chance to grow. It's just it's a faff warming 30ml to add it to the 90ml and no doubt it would end up hotter rather than same temp! But just wondering what the "done thing was", ordinarily I wouldn't mix milks of diff temps if they weren't to be drunk imediately.
