Natural Glass Baby Bottles Gentle & Extra Slow Flow - Newborn Bottle

In this review the focus is on a three pack of 8 oz borosilicate glass bottles designed for breastfed newborns who need a gentle, slow flow transition from breast to bottle. The single biggest reason to consider these bottles is the soft, breastlike nipple shape and new nipple guidance points that encourage a correct latch and natural suction habits, which makes switching between breastfeeding and bottle feeding easier for many families seeking a more natural feeding experience.

Key Features

• Soft and Anug-Fitting Nipple: The nipple is shaped to mimic the breast so babies can maintain familiar latch and sucking motions when moving between breast and bottle.
• Premium Borosilicate Glass: The bottle body is heat-resistant and free from BPA, BPS, phthalates and other toxins for a safer feeding option.
• Laser Engraved Body: Markings use laser engraving instead of ink printing to avoid lead and surface inks that can wear off over time.
• New Nipple Guidance Points: Subtle design points on the nipple help train appropriate suction habits and encourage correct latch technique.
• Easy to Clean and Sterilize: The simple construction disassembles easily for cleaning and can be sterilized in a bottle warmer, microwave sterilizer or in boiling water.
• Included Set: The pack includes three 8 oz bottles fitted with a slow flow M nipple suitable for young infants.

Who It's For

These bottles suit parents of breastfed newborns who want a glass alternative without plastics and a nipple that closely mimics the breast to reduce nipple confusion. They are also a good choice for families prioritizing heat resistance and easy sterilization for regular bottle use.

Those who prefer ultra-slow newborn-specific nipples, need clear multi-size nipple packs in the same purchase, or want a lightweight plastic bottle for travel may want to compare other options; this set emphasizes glass durability and breastlike feeding over ultralight portability.

Pros & Cons

Cons

• The flow rate receives mixed feedback from customers, with some finding the included M slow flow faster than expected.
