I am bottle feeding my newborn who wakes a few times through the night wanting to feed. Trouble s thati if I make up a bottle with powder formula milk it should be used within 2 hours but then that means inevitably that I am up at all hours making fresh bottles. What do you all do, is this just how it is or am I missing a trick? If it were me I would be tempted to but the pre-made ready to go formula for the nights but DP is against the cost of this as opposed to formula.
