DD is now 5 wks old. I am combined feeding. I am having problems with my supply so I just started to express. I tried an hour back for 45 mins and managed to get just half an ounce altogether from both sides.
Anyway, I have now put it in the fridge in a sterlized bottle and I understand it will last there for 24 hours.
I will try expressing again in half an hour. What I want to know is, can I mix whatever I manage to express now with the milk already in the fridge?
