Types of baby bottles
Anti-colic / vented
An internal vent or tube reduces air intake to cut gas, spit-up, and colic.
Wide-neck
A breast-like nipple shape that eases breast-to-bottle transitions.
Glass
No plastic chemicals and easy to sterilize; heavier and breakable.
Silicone
Soft, squeezable, and shatterproof — pricier but durable.
What to look for
- ✓Buy one or two to test acceptance before committing to a full set.
- ✓Match nipple flow level to your baby’s age to avoid over- or under-feeding.
- ✓Fewer parts = faster cleaning and fewer places for mold.
- ✓Check it pairs with your breast pump if you pump and bottle-feed.

Frequently asked
How many bottles do I need?
For exclusive bottle-feeding, 6–8 of your baby’s preferred bottle. If you combo-feed, 3–4 is usually enough. Start small until you know which bottle your baby accepts.
Do anti-colic bottles really work?
For gassy or reflux-prone babies, venting systems can noticeably reduce air swallowing and spit-up. Not every baby needs one — but they’re a common first fix for fussiness.
When do I move up a nipple flow level?
When feeds take much longer, baby seems frustrated, or they’re sucking hard with little reward. Go up one level at a time.

- How fast milk comes out; numbered slow → fast to match baby’s age.
- Vent system
- A tube or valve that lets air bypass the milk to reduce swallowed air.
- Nipple confusion
- When switching between breast and bottle disrupts latch — wide-neck shapes help.
