Starting from the earliest weeks, this two-pack pairs a 3 oz bottle and a 5 oz bottle to follow your newborn pace. We craft each body from smooth borosilicate glass and top it with our soft silicone nipples. Built-in vents allow continuous flow, while the four-piece assembly keeps daily routines simple.

We make these bottles from clean borosilicate glass that resists thermal shifts and contains no BPA, BPS, or phthalates. The clear material stays bright through frequent wash cycles and everyday use.
The set includes a compact 3 oz bottle for early feeds and a 5 oz bottle as intake increases. Clear volume markings help you track milk levels accurately from zero through three months.
We include an Extra Slow flow nipple for newborns and a Slow flow nipple for the next step. The flexible silicone shape encourages an easy latch while internal vents balance air pressure.
Each bottle consists of just four parts, including the collar, cap, glass base, and nipple. The wide-neck opening gives you plenty of room for quick hand washing and fast reassembly.
When I was pregnant I was dead set on using glass bottles, but I would be lying if I said I wasn’t worried or second guessing if they would be the right move for a baby. They have made my breastfeeding experience seamless with the way the nipple lends itself as a natural transition to bottle feeding. It passes the triangle test and the glass is durable that I’m never worried about having it crack or chip while feeding to my little one.
We absolutely love these bottles. My baby uses bottles during the day and nurses at night. He's not had any issues latching and is doing amazing switching between. Also I have dropped these an embarrassing amount of times even on tile and they have never broken.
