why are u pumping so soon? it is not recommended to start pumping until 4-6 weeks once breastfeeding is well established and to avoid oversupply which can lead to an infection such as mastitis.

Yes very normal.

Yes, pumping is not a measurement of how much you're producing because a baby can get a not more out... I've been breast feeding my little due almost 4 months and I'll get about a 1 oz each boob when I pump like 2+ hours after his last feeding

I would say it's all normal. You won't be able to pump out as much as baby can nurse out of you.
