The short answer
By 31–36 months, an open or straw cup can be the usual way to drink. If a bottle is still part of the routine, identify when it is used, replace daytime bottles first and create a soothing bedtime routine without milk in bed. Bottle weaning is separate from breastfeeding. Ask your child’s clinician if cup drinking is persistently difficult or there are feeding or growth concerns.

Keep in mind
- Bottle weaning and breastfeeding are separate decisions.
- Replace bottle routines gradually, starting with easier daytime occasions.
- Offer milk before toothbrushing and use a cup; avoid milk bottles in bed.
Why is it helpful to move on from a bottle?
Sipping milk or sweet drinks throughout the day may reduce appetite for meals. When milk stays against the teeth for a long time, especially during sleep, tooth-decay risk rises. The overall pattern matters more than a single bottle.
How can you make a gradual plan?
For a few days, note when your child asks for a bottle and whether it is linked to thirst, hunger, comfort or sleep. Start with an easier daytime bottle and offer a cup instead. Keep the change consistent before moving to the next occasion.
How can you change the bedtime bottle?
Offer milk in a cup before the bedtime routine, then brush your child’s teeth. Replace the bottle’s soothing role with a short story, song, cuddle or familiar phrase. Stay close and calm if your child protests, and repeat the new routine.
What if your child refuses a cup?
Offer a small amount in an open or straw cup and let your child choose between two suitable cups. Model drinking together at the table. Do not withhold fluids, force drinking or make the bottle a source of shame.
How can all caregivers stay consistent?
Agree which bottle is being phased out and what will replace it. Share the same plan with childcare and other caregivers. If illness or a hard week interrupts progress, return to the last manageable step without blame.
When to seek support
Some signs need emergency help; other concerns can be discussed with your child’s healthcare team.
- Persistent refusal to drink from a cup, very little urine, dry mouth or unusual lethargy.
- Repeated coughing, choking, pain or difficulty swallowing drinks.
- Very high milk intake with poor appetite, growth concerns or visible tooth decay.
