Overview
Haakaa's Gen.3 wide neck baby bottle is a 4.2 oz (120 ml) glass bottle built for newborns from birth, sold as a single unit. Glass construction skips the plastic taste and surface scratching some parents want to avoid, and the wide neck matches haakaa's own nipples plus most other wide neck brands.
Glass bottles trade a little extra weight and breakage risk for a smooth surface that will not scratch or cloud the way older plastic bottles can after repeated sterilizing. At 4.2 oz this is the smaller of haakaa's glass sizes, sized for the frequent, smaller feeds typical of the newborn stage rather than a growing baby's bigger appetite.
- 4.2 oz / 120 ml capacity
- Wide neck design
- Glass construction
- Rated for 0 months and up
Who it's for
Suits parents of a newborn who want a glass bottle and are comfortable with something that can chip or crack if dropped on a hard floor. Less suited to anyone needing a break resistant bottle for daycare or busy multi caregiver households, or a parent who already needs a larger 8-9 oz size for an older baby.
Strengths and trade-offs
Drawn from this product's published specifications.
- Glass body resists scratching and staining from repeated sterilizing
- Wide neck fits haakaa nipples and most other wide neck bottles
- Sized for newborn feeds at 4.2 oz
- Glass adds breakage risk if dropped
- 4.2 oz capacity means a resize is likely as baby grows
Performance notes
As a wide neck glass bottle, it should pair with haakaa's own nipples and most other wide neck nipple brands, and the glass body wipes clean and boils or steam sterilizes without the cloudiness plastic can pick up over repeated cycles.
