Hi! So I unfortunately wasn’t able to get the Spectra manual breast pump, so I picked up a Medela Harmony. I don’t typically use narrow neck bottles nor Medela parts, so I was wondering if anyone had suggestions on hacks to make my other parts work with this new pump.

I currently use Pumpables Liquid Kit as my primary flanges and Spectra as my back up. I have a conversion kit for both wide to narrow neck bottles and narrow to wide neck.

My main concern is the flanges and how to possibly use my silicone ones with the Harmony without needing to buy a bunch of new things. Any advice helps!

Attached is the Pumpables Liquid Kit, Medela Harmony Pump, and the standard Spectra flanges.
