We make these three-ounce bottles from thermal-shock resistant borosilicate glass to suit the smallest feedings. Each bottle comes fitted with an extra slow flow silicone nipple featuring guide points that encourage an intuitive latch. The compact glass body warms evenly and cleans down quickly after every meal.

We form each three-ounce vessel from durable borosilicate glass that is free of BPA, BPS, and phthalates. The nonporous surface resists odors and handles sudden temperature shifts from warming to sterilizing without wear.
Our size SS silicone nipples release liquid at a gentle rate suited for preemies and newborns. Guided latch points along the ultra-soft tip help your infant build steady suction habits that mimic natural breastfeeding movements.
Built-in vents route air away from the liquid path and back into the base of the glass bottle. This continuous airflow prevents the nipple from collapsing, allowing your baby to feed smoothly without swallowing large air pockets.
Each bottle consists of four straightforward parts that take seconds to assemble and wash. The wide neck allows easy access with standard bottle brushes, and every component can be sanitized in boiling water, microwaves, or electric sterilizers.
I originally bought 2 of the 3oz bottles to test and see how my twins liked them, and we’ve definitely been back to purchase more! With twins I am mainly pumping and bottle feeding. These bottles have made it possible to also latch my less experienced breastfeeding babies a few times a week.
These are our favorite bottles we have used for our baby. Now that he’s bigger he uses the 8oz bottles almost exclusively, but the extra slow flow of these was perfect for when he was a tiny baby. We’ve never had any issues with leaking or chipping or anything of the sort, and they’ve held up well through nearly a year of washing and sanitizing.
