Nursing and pumping
$$$
Spectra
Made in South Korea
Closed-system electric pump with a silicone membrane barrier, so milk never enters the tubing or motor, and a standard bottle thread that takes glass.
Most insurance plans cover a breast pump, and Spectra is among the most commonly covered, so it is often available at no cost.
$$$
Mila's Keeper
Designed in the USA and made in Italy
Borosilicate glass bottles with platinum silicone sleeve and lid, so milk is pumped, stored, and fed from glass without transfer.
