Babies love routine, and few habits run deeper than the bottle. To a little one it means warmth, comfort, and closeness, so trading it for a cup can feel like losing a small friend.
The payoff is worth the fuss. Pediatricians want babies off the bottle during the second year to protect new teeth and build grown-up drinking skills, and the switch goes far smoother with good timing and a gentle plan.
These nine steps walk you through the move from bottle to sippy cup, from the first practice sips around six months to the very last bedtime bottle.
Key Takeaways
- Start early: Offer a sippy cup with solid foods around six months so your baby practices sipping long before the bottle disappears.
- Ease the flow: Pull the spill-proof valve out at first so liquid moves without a hard suck, the way a bottle does.
- Pick a straw or soft spout: A straw cup or soft silicone spout builds a mature swallow better than a hard sippy spout.
- Finish by 12 to 18 months: The AAP recommends completing the bottle-to-cup switch between 12 and 18 months, with an open cup by about age two.
When To Introduce a Sippy Cup
Introduce a sippy cup when your baby starts eating solid foods, usually around six months old. At this stage you are not trying to replace nursing or bottle-feeding. You are helping your baby build the mouth and hand muscles needed to hold a cup and swallow from it.
Early, low-pressure practice makes the real switch easier later. Wait too long and the bottle turns into a security object that is far harder to give up. The American Academy of Pediatrics recommends finishing the move off the bottle sometime between 12 and 18 months, and drinking from an open cup by about age two (1). Dropping the bottle on that timeline also lines up with your child’s first birthday milestones.
Why You Should Switch
Hanging onto the bottle too long is more than a habit; it carries real health costs. Moving your baby to a cup helps you head off (2):
- Tooth decay: Milk and juice sugars pool against new teeth and cause early childhood caries.
- Ear infections: Drinking while lying down lets fluid collect behind the eardrum.
- Picky eating: Filling up on liquid calories leaves little appetite for solid food and its nutrients.
- Dental misalignment: Constant sucking can reshape the palate and push teeth out of line.
- Obesity: A bottle makes it easy to sip extra calories all day without noticing.
How to Transition from Bottle to Sippy Cup
Every baby moves at a different pace. Some take to a cup in a day; others need a few weeks of patient practice. These nine steps stack the odds toward a calm, tear-free switch.
1. Start Early
Offer the cup alongside first solids. Tip the spout gently toward your baby’s mouth so they see and taste that liquid comes out.
Do not expect a full serving right away. Early on, the point is coordination and muscle memory, not volume. The sooner your baby treats the cup as normal, the fewer tantrums you will face when the bottle finally goes away.
Consider giving your baby an empty sippy cup to play with. Allowing them to handle the cup may make them more likely to accept it when you use it with liquids. When your family is eating, let your baby have a sippy cup. Then see if you can get them to mimic you as you take a sip from your own cup.

Most sippy cups ship with a spill-proof valve. It saves your carpet but frustrates a beginner, because it takes a firm suck that a bottle never asked for.
Take the valve out so liquid flows freely at first. It will be messy, but it teaches your baby that tipping the cup delivers a drink. Once they have the motion down, drop the valve back in.
3. Start With a Silicone Spout or Straw
A hard plastic spout feels nothing like a soft bottle nipple. Bridge the gap with a soft silicone spout or, better yet, a weighted straw cup.
Straw and open cups do more than ease the switch. Speech and feeding therapists point out that they build a mature swallow, while a rigid sippy spout keeps the tongue pushed forward in the same infant suckle your baby used on the bottle. Many bottle brands also sell transition lids that swap a spout onto the bottle body your baby already knows.
4. Use Familiar Liquids
Water is the best drink for your baby’s teeth, but it has no flavor to sell a strange new cup. If your baby turns away, start with the breast milk or formula they already drink.
When the cup is new but the taste is familiar, acceptance comes faster. Dip the spout in milk so the first touch tastes right. Once your baby drinks happily, pediatricians suggest moving to plain water at mealtimes so the cup does double duty for teeth and hydration.
5. Offer a Sippy Cup Instead of a Bottle
Once your baby has the mechanics down, start trading the cup into the daily routine.
Swap one bottle at a time. If you usually give a mid-day bottle, offer the sippy cup with formula or breast milk in its place. If you nurse exclusively, offer the sippy cup with meals rather than at the breast.
6. Go Easy on the Nighttime Bottle
The bedtime bottle is usually the last to go, because it soothes as much as it feeds. Phase it out by slowly cutting the ounces and offering a filling, protein-rich snack before the bedtime routine begins.
Separate feeding from sleep, too. If you normally feed in the nursery, move the last drink to a bright living room. That breaks the link between sucking a bottle and drifting off, which is what makes the habit so sticky.
7. Quit Cold Turkey
For some families, a slow wean just drags out the protest. If gradual steps stall, you can clear every bottle out of the house at once.
Expect a rough day or two, then a fast finish. This method works best with older babies and toddlers who can grasp that the bottles are simply “gone.”
8. Follow Through
Consistency is your strongest tool. Once the bottles are gone, handing one back during a meltdown resets all of your progress.

9. Quit All Bottles Around Age One
Aim to finish the switch during the second year, ideally between the first birthday and 18 months. After age one, toddlers form stronger attachments to comfort objects, so every extra month makes the bottle harder to retire.
