Baby bottle nipple flow selector
Use feeding pace, common too-slow and too-fast cues, and your current bottle stage to decide whether to stay put, size up, or size down, then compare what that means across major bottle brands.
Why this page exists
Search results for bottle nipple size by age are usually thin brand charts. Real feeding decisions are more awkward than that. A bottle can be too slow because the baby is working too hard, or too fast because the baby is losing control, and the brand numbers are not interchangeable.
- Maps symptom patterns to a practical next step instead of pretending age alone decides everything.
- Shows how the recommendation translates across major bottle families.
- Keeps thicker feeds separate, because they often need their own teat rather than a normal one-step jump.
Too slow vs too fast
- Feeds drag on far past the usual window and baby still seems unsatisfied.
- Teat collapse, repeated loss of seal, clicking, or hard sucking effort.
- Baby tires out before a normal feed is finished.
- Dribbling, gulping, coughing, sputtering, or a panicked look.
- Feed finishes unusually quickly because milk is flooding in.
- Baby seems winded, extra gassy, or needs frequent forced pauses.
Scope
Important: this page is a practical selector, not medical advice. If feeds are consistently painful, weight gain is a concern, or the baby is choking or struggling to feed safely, talk to a clinician or feeding specialist.
