How to fix it
Work through these in order, the most common causes come first.
Start With the Basics
Temperature: Offer milk at a comfortable warmth, not cold from the fridge.
A baby used to warm milk from breastfeeding may reject a cold bottle even if everything else about it is right.
Who's offering it: Some babies specifically refuse a bottle from the parent who breastfeeds them, expecting the breast instead, but will accept the same bottle from a different caregiver.
This is common and not a sign of a bottle problem.
Timing: An overtired or extremely hungry baby may reject anything unfamiliar out of frustration.
Diagnosing Your Specific Problem
Baby gags or pulls away quickly: often a flow rate that's too fast.
Try a slower flow level and see if the reaction changes.
Baby seems to work hard and gets frustrated without much milk: often a flow rate that's too slow.
Try moving up one flow level.
Baby accepts the bottle from one caregiver but not another: points to an association with breastfeeding rather than a bottle issue.

FAQ
Common questions
Why does my breastfed baby refuse every bottle?
This is common and usually comes down to a combination of factors rather than one single cause: nipple shape and texture feeling different from a breast, flow rate being too fast or slow, temperature being off, or the baby associating the bottle-feeding parent with breastfeeding and expecting the breast instead. Trying a wide, breast-shaped nipple and having someone other than the primary breastfeeding parent offer the bottle are both common first steps.
How long should I try a new bottle before giving up on it?
Give a new bottle a genuine trial across several separate feeding attempts, not just one, ideally when the baby is calm and moderately hungry rather than overtired or frantic. A single refusal doesn't mean the bottle is wrong; a pattern of refusal across multiple calm attempts is a stronger signal to try something different.
Does nipple flow rate really matter for bottle refusal?
A flow that's too fast can cause a baby to gag, choke, or pull away defensively, while a flow that's too slow can lead to frustration and giving up before getting enough milk. Matching flow level to age and feeding stage, and moving up a level only when a baby seems to be working too hard for milk, is a real and common fix for refusal.
Should I try a different bottle brand if my baby refuses the first one?
It's a reasonable next step after ruling out flow rate, temperature, and who's offering the bottle, since nipple shape and texture genuinely vary between brands. A wide, breast-shaped nipple (Philips Avent Natural) or a soft, skin-like silicone body (Comotomo) are common choices when a baby has rejected a firmer or differently shaped nipple.
