DS is 15 weeks, EBF and still waking lots through the night 
Whilst I know this is completely normal I'm exhausted and I've asked DP to do one night so I can get a full nights sleep. But logistically how does he do this? I'd like to express but will have to express over a few days to have enough for the whole night, so stupid questions alert...
I know breastmilk can be stored at room temp for 6 hours and in the fridge for 6 days. So can I express over a few days, keep in the fridge and then take out at say 10pm and keep at room temp until 4am?
If DS will take milk cold straight from the fridge, could I take out of fridge at 10pm and keep in a cool bag overnight?
If DS doesn't finish a bottle, does the rest of that bottle have to be discarded, and if yes am I best portioning out the milk into 6 bottles so DP won't have to throw a load away?
