I would breastfeed then pump afterwards, and I always had enough to store in the lil freezer baggies that came with breast pads. I never ran out of milk and defrosting the milk was easy, just let it sit in a bowl of hot water. My baby didn't care that the milk wasn't warm.
I had too much milk the first two times... I would just dump it.. I hated freezing and unfreezing the bottles
You should be able to have extra if you start pumping as soon as your milk comes in good. Pump. Pump. Pump thats what I did and I had a ton of milked stored
I always pumped after and eventually it slowly grew to more so I was able to have extra
I breast fed my daughter and I always had extra to put in the fridge. I just had to pump at the time she usually had to feed and I kept producing alot of milk. Hope this helps:-)
Everyone is different. My body doesn't respond to a pump. There are ways to increase your milk supply. If you are on fb look up breast is best
