Okay, following disastrous expressing experience of last week, yesterday morning I expressed 2oz of milk. This went straight into the back of the fridge in a bottle with the lid on top and there it remains. Can I add whatever I express tomorrow to it and freeze it straightaway? The expressed milk has separated, is it ok to add fresh to this and then freeze? My memory says yes but a half hearted look at Kellymom this morning whilst trying to feed DD produced no answer and I'm now on my phone. TIA
