The short answer
By 31–36 months, an open or free-flow cup can be the usual way to drink. If your child still uses a bottle, notice when they ask for it, replace daytime bottles first and build a soothing bedtime routine without milk in bed. Stopping bottles is separate from breastfeeding. Speak to your health visitor, dentist or GP if cup drinking remains difficult or you are worried about feeding or growth.

Keep in mind
- Stopping bottles and stopping 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. Milk left around the teeth for long periods, particularly during sleep, can increase tooth-decay risk. The overall pattern matters more than one bottle.
How can you make a gradual plan?
For a few days, notice 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 predictable before moving on to another bottle.
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 comfort with a short story, song, cuddle or familiar phrase. Stay calm and reassuring if your child protests, and repeat the new routine.
What if your child refuses a cup?
Offer a little drink in an open or free-flow cup and let your child choose between two suitable cups. Practise together at the table. Do not withhold drinks, pressure your child to drink or make the bottle a source of shame.
How can all carers stay consistent?
Agree which bottle is being phased out and what will replace it. Let nursery and other carers know the plan. 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 drowsiness.
- Repeated coughing, choking, pain or difficulty swallowing drinks.
- Very high milk intake with poor appetite, growth concerns or visible tooth decay.
