Don’t stress about it, your milk most likely haven’t kicked in yet. Just feed FM and on the other hand, pump to stimulate the milk regardless the amount. My baby was on mixed feeding for the first month too cause I didn’t have enough to feed her. Drink more water, pump or latch as much as you can 😊 Try offering baby the nipple again, it takes a few tries sometimes before they get it.
