- Grows with baby: 4 oz and 8 oz sizes now; jars can later convert to straw cups with add-on tops.
- Universal fit with any regular-mouth mason jar—easy to expand, replace, or upsize as you go.
- Pump-friendly: adapters let you pump directly into the jars to skip pouring and extra containers.
- Easy 120-day returns and baby-first guarantee if it’s not the right fit.
