I’m a FTM here...

3 weeks postpartum & im strictly BF. After each feeding I pump both sides & get about 1 to 1.5 ounces total. Should I be looking for ways to increase my milk supply or will it increase in time ? I’m worried because I plan to go back to work between 6-8 weeks pp. I’m afraid I won’t start producing enough milk to have stored away for my LO. I try to pump before feeding to see what I produce but she always wakes up before I get the chance.
