Weaning your baby off the bottle: calmly and without tears

Updated August 25, 2026

The bottle is convenient and familiar, and giving it up is something a baby — and often the parents — would rather not do. But over time it turns from a help into a hindrance: long sucking from a bottle is worse for teeth and speech than drinking from a cup, and it gets in the way of moving on to a more grown-up way of drinking.

Below: when to start, why the timing matters, how to wean off the bottle gradually and gently, the one rule about sleep you must not break, and what to do if your child flatly refuses the cup.

When to wean off the bottle

The guide is this: offer a cup — open, straw or sippy — from around 6 months, and aim to have your child off the bottle by about 12–18 months. Meeting the cup early makes the move feel natural: by the age when the bottle should go, your child already knows another way to drink.

Prolonged bottle use is linked to tooth decay, more ear infections and overfeeding. That does not mean rushing to snatch the bottle away — but there is no reason to keep putting it off either.

Why the timing matters

The main thing is teeth. When a child sucks from a bottle for a long time, especially falling asleep with it, milk or juice pools around the teeth, and that leads to cavities. From a cup the liquid does not bathe the teeth for anything like as long, so a cup is better for the enamel — and better for speech, since drinking from a cup uses the muscles of the mouth differently from sucking.

How to wean — gradually

Introduce the cup early. From 6 months, offer a cup with meals so it becomes a normal part of the table well before you start taking bottles away.
Drop one feed at a time. Replace the bottle with a cup at a single feed and wait until your child is used to it before dropping the next. Start with daytime feeds — they are the easiest to change.
Make the bottle "boring". Put only plain water in the bottle, and offer milk and anything more interesting in the cup. Then the cup becomes more appealing than the bottle all on its own.
Keep the bedtime bottle for last. It is usually the hardest: it is comfort and a falling-asleep ritual as much as food, which makes it the toughest one to let go.
Offer comfort another way. Replace the evening bottle with a different ritual — a predictable routine, cuddles, a bedtime story. What your child needs is not the sucking itself but the sense that all is calm and a grown-up is near.
Be consistent and patient. The move usually takes a couple of weeks, and that is fine. Sharp steps backwards unsettle a child more than slow but steady progress forward.
Let them choose the cup. Let your toddler pick their own cup — with a favourite picture or colour. When the cup is "theirs", drinking from it is more fun.

The key rule about teeth

Never put your baby to bed with a bottle, and do not let them walk around all day sipping milk or juice from one. Both are a direct route to tooth decay: less saliva is made during sleep, and the sugary liquid sits on the teeth all night. If a bottle in the cot is still hard to avoid for now, let it hold nothing but plain water.

Do not rush it or stop abruptly

There is no need to stop abruptly if it distresses your child. A gradual move is both kinder and works better: the child has time to get used to the cup and to find new comfort in place of the bottle. It is completely normal for the whole process to take a few weeks and for the bedtime bottle to be the last to go. That is not a sign you are doing anything wrong.

If it isn't working

If your child refuses every cup and drinks very little, loses weight, or you are simply worried they are not getting enough, talk to your paediatrician. A health visitor can also help you choose a cup and shape the move. This is not a dead end but an ordinary situation, and there is someone to work it through with.

And an important point: weaning off the bottle is about the bottle, not about stopping milk. Your child still needs milk — just from a cup now. You are changing the way they drink, not taking milk out of their diet.

How to keep track of the move

It is easy to lose the thread during the switch, especially when different grown-ups take turns caring for the baby. Noting which feeds you have already replaced with a cup and how your child took to it makes the plan visible — and easier to keep the same between mum, dad and grandparents. Then no one accidentally brings back a bottle you had dropped, and the forward progress is not knocked off course.

Frequently asked questions

At what age should I wean my baby off the bottle?

Offer a cup from around 6 months and aim to be off the bottle by about 12–18 months. Meeting the cup early makes the move natural and less of a struggle.

Can I give a bottle at bedtime?

Do not put your baby to bed with a bottle of milk or juice — the liquid sits on the teeth all night and leads to cavities. If a bottle in the cot is still hard to avoid, fill it with plain water only.

How do I wean if my child does not want to?

Go gradually: drop one feed at a time, starting with daytime ones, make the bottle "boring" (water only), and offer milk in the cup. Keep the bedtime bottle for last and replace it with a different falling-asleep ritual.

Does weaning off the bottle mean stopping milk?

No. Your child still needs milk; only the method changes — now they drink it from a cup instead of a bottle. You are removing the bottle, not the milk.

How long does moving to a cup take?

Usually a couple of weeks, and that is normal. The bedtime bottle is most often the last to go because it is tied to comfort before sleep. There is no need to rush or to take it away abruptly.
