I've been using a silicone breast pump during night feeds, just to catch drips and try to limit the mess. I'm generally getting approx 2oz per feed, and feeding three or four times through the night.
So far I have just been tipping it away, as DS was exclusively BF and I already had a few bags of expressed milk sitting unused in the freezer. However we are just starting to introduce occasional bottles, so it makes sense to stop pouring milk away.
If I take a large empty bottle (8oz?), and one of those insulated cool bags with an ice pack, upstairs with me in the evening; can I just decant milk into that through the night; then pop it in the fridge in the morning? It would be nice to not have to go downstairs to decant and refrigerate milk after every feed, but obviously I don't want to risk giving DS 'off' milk. Also, if I sterilise the silicone pump just before bed each evening, can I keep using it for the three or four feeds during the night, or do I need to re-sterilise it each time?
