Introducing a bottle of expressed milk: A Gradual Approach

A bottle of expressed milk gives another caregiver a way to feed your baby, but it may feel unfamiliar at first. Learning it can take a few calm attempts. The aim is a comfortable feed with enough milk overall, not getting your baby to accept a particular bottle at any cost.
Choose timing that fits the reason
If there is no urgent need, many families practise once direct breastfeeding feels established. If your baby needs extra milk sooner, do not postpone feeding to reach an arbitrary age. Ask your care team which method is appropriate and how to support breastfeeding if you want to continue it.
For a well baby learning something new, try an offer when they are calm and showing early interest in feeding, before intense crying. Our feeding cues guide explains signs such as rooting and bringing hands towards the mouth. Another familiar caregiver may find a comfortable way to offer the bottle.
Set up a responsive feed
Prepare milk and equipment safely. Our thawing and warming guide explains preparation; milk does not have to be warm if your baby accepts it cool.
Hold your baby close, partly upright with their head supported. Touch the teat gently to the upper lip and allow them to take it rather than pushing it into the mouth. Keep the bottle nearly horizontal, slightly tipped as needed, to avoid a fast continuous flow.
Watch throughout the feed. Pauses, turning away, pushing the teat out or milk spilling can signal a need to slow down or stop. Give breaks and avoid urging your baby to finish. Never prop a bottle or leave a baby feeding alone.
Keep practice from becoming pressure
If your baby becomes upset, pause, comfort them and reassess. Do not withhold their usual milk to make them hungry enough to accept the bottle. If repeated attempts are difficult, ask a feeding professional to observe rather than buying many products with promises to imitate the breast.
Frequent coughing, breathing difficulty during feeds, consistently poor intake or concerns about growth need assessment. A baby who cannot feed, is difficult to wake or has serious breathing difficulty needs immediate medical help, not another practice session.
Include your own milk removal plan
If bottles regularly replace breastfeeds and you want to maintain milk production, discuss when to express. Our pumping schedule guide covers that planning. The right routine depends on how many feeds are replaced and whether your goal is full or partial breastfeeding.
Share the same approach with everyone feeding your baby, including storage limits and when to ask for help. A flexible plan can change as feeding becomes easier or your circumstances change.
