Pumping troubles...

Megan • Baby Boy born on 08/16/18

My son is 4 weeks old, I pumped for my first time yesterday & after what seemed like forever, I barely got 2 oz (both boobs included).

I’m not sure if I’m doing something wrong or if I just need to keep trying so my body gets used to it? I know my LO is getting fed, he’s constantly swallowing & has a wet diaper every time I change him, and he’s gaining weight.

Help a new mama out?
