Hello. I have to return to work in November (a teacher and took FMLA leave) and I do leave the house sometimes. I only have about 5 bags of milk...well make that 3 bags (my MIL unthawed some) in the freezer. Should i pump more often. I only pump in the morning if my LO didn't wake up for longer then usual and I am engorged. I had an oversupply problem before and I don;t want that to happen again, that's why I haven't pumped much, and I don;t really like it. So how much should i have? I have an upright freezer so the milk should keep longer right?
