Does it matter what your main pump is?

I used the spectra with my first and now that I have my second, I got a hands-free, wearable pump. I’ve heard that you aren’t supposed use wearable pumps as your main pump.

Any insight on this? I’m 6 weeks pp and finding myself more and more on the go. Even at home, it’s way more convenient to use the wearable pump.

I haven’t seen it effect my supply. Is this something that could affect it though?
