NANOBÉBÉ Nanobebe Breast Pump Adapter Set- Compatible with all standard breast pumps, Pumps Directly into Nanobebe Bottles, One Size

I have three different breast pumps (I know it took me a couple tries) but this adapter works with all three of them! I can easily pump into the NanoBebe newborn bottles when I’m on the go or out of breastmilk storage bags. Will definitely buy again.

I never got to use this - I assumed I'd need it to connect the nanobebe silicone bottles to one of the pumps in the description, but as it turns out the silicone bottles seem to fit without needing an adapter and there's no way to fit this adapter to the nanobebe silicone bottles anyway.

I use this to pump from my spectra equipment into glass 8 oz regular mouth Mason jars. It's a perfect adapter and very easy to clean. You do need to buy a package for each side if you're pumping from both sides.

I’m not using these to pump, but rather to warm up breast milk that’s stored in mason jars. I purchased the Lucky Black Cat portable warmer that comes with several adapters. You can use one of their’s (39mm) with one of these to connect a mason jar.

I bought these to pump into mason jars and I was thrilled that they fit both the 4 oz and 8 oz regular mouth, smooth Ball mason jars AND all the Medela pumping parts that I already had (see video). I've used these maybe 10 times so far and have had no leakage or anything. These are an awesome hack for using mason jars to pump into, store/freeze, and then pop on a Comotomo or Boon nipple and you can feed directly from the mason jar.These adapters make mason jars just as easy to use as the plastic Medela storage bottles. The only annoying thing is that they are sold as individuals, but most women have 2 breasts!
