Slow flow
A common starting point for young babies. Check the manufacturer's age and flow guide.
How to Choose the Right Baby Bottle
The right bottle is the one your baby can feed from comfortably and you can clean properly. Use this guide to narrow the choices without buying a full cupboard first.
Your four-step selector
Choose in this order
-
1
Feeding stage
Newborn, older baby, expressed milk, formula or mixed feeding changes what is practical.
-
2
Bottle size
Smaller bottles are lighter for early feeds. Larger bottles become useful as intake increases.
-
3
Material
Compare weight, break resistance, visibility and cleaning—not just appearance.
-
4
Teat and flow
Start conservatively and watch the baby. Brand age labels are guides, not deadlines.
Teat flow: let the feed tell you
Medium flow
Consider only when the current teat seems consistently too slow and feeding skills are ready.
Faster or variable flow
Use when appropriate for the liquid and baby, following the bottle maker's instructions.
Flow may be too fast
- Coughing, gulping or spluttering
- Milk leaking around the mouth
- Pulling away or struggling to pause
- Feeds feel rushed or uncomfortable
Flow may be too slow
- Teat repeatedly collapses
- Baby becomes frustrated or tired
- Feeds take unusually long
- Strong sucking with little milk transfer
These signs can have more than one cause. If feeding is persistently difficult, painful or worrying, speak with a pediatrician or qualified feeding professional.
Material comparison
| Material | Best for | Trade-offs |
|---|---|---|
| Food-grade plastic | Lightweight everyday use and travel | Inspect for scratches, clouding and damage; replace as directed. |
| Glass | Clear viewing and long-term durability | Heavier and breakable; use a suitable protective sleeve if recommended. |
| Silicone | Soft grip and reduced break risk | Can be harder to see through and may cost more. |
What about teat shape?
Standard, wide-neck, orthodontic and “breast-like” shapes can all work. A comfortable seal, steady swallowing and an easy-to-clean design matter more than the marketing name. Anti-colic vents may reduce swallowed air for some babies, but no bottle prevents every episode of wind or crying.
A calmer bottle feed
- Hold your baby close and semi-upright, supporting the head and neck.
- Invite the teat rather than pushing it into the mouth.
- Keep enough milk in the teat to limit air intake without forcing a fast flow.
- Pause when your baby pauses; watch for turning away, relaxed hands or loss of interest.
- Never prop the bottle or force your baby to finish.
Clean, sterilise and prepare carefully
- Wash hands and clean the preparation surface.
- Wash bottles and teats promptly with hot soapy water and dedicated brushes.
- Rinse before sterilising and follow the steriliser manufacturer's instructions.
- NHS guidance recommends sterilising feeding equipment until at least 12 months.
- For powdered formula, measure water first and follow the formula label exactly.
- Never microwave a bottle; hot spots can burn.
- Discard formula left after a feed.
