Will I get less milk pumping with a wearable?

Hi, I’ve moved to EP after breastfeeding stopped working for me and my baby when he turned 3 weeks old. He’s now 6 weeks and he’s very demanding food wise, needing about 4-5 ounces a feed!

At the moment with my spectra 2 and haaka I can pump between 3-4.5 ounces a session but I’ve missed sessions due to being caught up with the baby. To avoid this happening I am considering investing in wearables so I can be more flexible with my pumps but I heard that people get less milk with wearables, and that would defeat the point for me. I’d probably be looking at supplementing two pumping sessions with a wearable and doing the rest with my spectra. I try to pump 7-8x a day.

I suppose I’m asking if I were to get a wearable can I still expect to see 3-4 ounces pumped? What has everyone else’s experience been?

Thank you. .
