When Should Your Baby Switch Cups? A Simple Age-by-Age Guide

One day, your baby is happily drinking from a bottle, and before you know it, they're reaching for your water glass or trying to hold a cup on their own. It's one of many exciting milestones in the first year, but it also raises a common question for parents:

When is the right time to introduce a cup?

The transition from bottle to cup isn't something that happens overnight. Every baby develops at their own pace, but introducing cups gradually can help support independence, oral development, and healthy drinking habits.

With so many options available, choosing the right cup can feel confusing. The good news is that each type of cup is designed to support a different stage of your baby's development. A soft spout cup is usually the easiest first step, while straw and 360° cups can be introduced as your baby's drinking skills improve. The key is to choose a cup that matches your little one's developmental stage and comfort level.

Here's a simple guide to help you understand which cup is suitable at different stages of your baby's journey.

Around 6 Months: Introduce an Open Cup or Soft Spout Cup

At around six months, your baby is learning so many new things—from trying their first foods to developing better hand control. It's also a good time to introduce a cup and let them enjoy a few sips of water with meals.

At this stage, your baby is still learning how to coordinate sucking, swallowing, and holding objects. The goal isn't to replace bottles immediately; it's simply to help your little one become familiar with drinking from something new.

Many parents find that a Soft Spout Training Cup (add link) is a comfortable first step because the familiar silicone spout feels similar to a bottle nipple, making the transition easier. Lightweight handles also make it easier for tiny hands to grip independently.

You can also offer small sips from an open trainer cup under supervision to help your baby practise natural sipping skills.

Expect spills—they're all part of the learning process.

Around 8–9 Months: Encourage Straw Drinking

Once your baby develops better hand-mouth coordination, introducing a weighted straw cup (add link) can be a great next step.

Unlike a regular straw, a weighted straw allows your baby to drink from different angles as they tilt the cup. Drinking through a straw also encourages lip closure, tongue coordination, and oral motor skills that support more mature drinking patterns.

Don't worry if your baby doesn't understand the straw immediately. Some babies figure it out within a day, while others may take several weeks.

A few ways to encourage success include:

• Offer the straw cup during meals.
• Demonstrate drinking from a straw yourself.
• Keep practice sessions short and relaxed.
• Praise your baby for trying, even if only a few sips make it into their mouth.

The goal is progress, not perfection.

Around 10–12 Months: Build Confidence with Independent Drinking

As babies approach their first birthday, they usually become much more interested in doing things by themselves.

This is the perfect time to encourage independent drinking.

Instead of expecting them to finish an entire drink without help, allow them to hold the cup, explore it, and practise lifting it to their mouth. Small moments like these help develop coordination and confidence.

A 360° cup (add link) can be a good option at this stage, as it lets babies drink from any point around the rim while helping minimise spills. It also encourages a natural sipping motion, similar to drinking from an open cup.

Spills will still happen, and that's completely normal. The goal is to help your baby build confidence with every sip.

Around 12 Months: Begin Reducing Bottle Use

The American Academy of Pediatrics (AAP) recommends introducing cups around six months and gradually transitioning away from bottles between 12 and 18 months. Prolonged bottle use may increase the risk of tooth decay and can sometimes make it more difficult for children to adopt mature drinking patterns.

There's no need to stop bottle-feeding suddenly. Instead, replace one bottle feed at a time with a cup over several weeks.

Many families find it easiest to begin with daytime feeds while continuing bedtime bottles until their child becomes more comfortable.

Taking it one step at a time makes the transition easier for everyone.

Choosing the Right Cup for Each Stage

Not every cup works for every baby.

When selecting a cup, consider your child's age, developmental stage, and comfort level.

• Around 6 months: Soft spout cups or supervised open trainer cups are ideal for introducing cup drinking.
• Around 8–9 months: Weighted straw cups help babies practise sipping while supporting oral motor development.
• Around 9–12 months: 360° cups encourage natural sipping and are a great bridge before moving to regular open cups.

Remember, the "best" cup is the one your baby is happy to practise with consistently.

Tips for a Smooth Transition

Every baby learns differently, but these simple tips can make cup training easier:

• Introduce the cup during mealtimes rather than when your baby is very hungry.
• Start with small amounts of water or expressed breast milk.
• Let your baby explore the cup without pressure.
• Avoid forcing the transition if your child isn't ready.
• Stay patient and celebrate small successes.

Some babies adapt quickly, while others need more time. Both are perfectly normal.

What If Your Baby Refuses the Cup?

It's common for babies to reject a new cup at first.

If this happens:

• Try offering the cup at a different time of day.
• Experiment with another style of cup.
• Let your baby watch siblings or parents drinking from cups.
• Continue offering it regularly without pressure.

Consistency is more effective than forcing the transition.

Supporting Every Sip

Learning to drink from a cup is more than just replacing a bottle—it's an important developmental milestone that encourages independence, coordination, and healthy oral habits.

Whether your baby starts with a soft spout, moves to a straw cup, or gradually masters a 360° cup, remember that every child follows their own timeline.

Dr. Brown's range of Soft Spout Transition Cups, Milestones™ Weighted Straw Cups, and Cheers360® Cups is thoughtfully designed to support babies through each stage of this journey, making the transition comfortable for little hands while giving parents greater confidence along the way.

After all, every little sip is another step towards growing up.
