When to Transition From a Bottle to a Sippy Cup (And Which Cup to Choose)

Making the move from a bottle to a cup is one of those milestones that can feel surprisingly daunting. One day your baby is happily taking a bottle, and the next you're wondering whether it's time to introduce a sippy cup, straw cup, or even an open cup.

There's no need to rush, but starting the transition at the right time can help support your little one's developing feeding skills and make mealtimes easier in the long run.

When Should Babies Transition From a Bottle?

Most babies are ready to start exploring cups from around 6 months of age, when they begin solids. While breastmilk or formula remains their primary source of nutrition, introducing a cup early helps them develop new drinking skills alongside learning to eat.

Many health professionals recommend aiming to transition away from bottles by around 12 months of age, although every child develops at their own pace.

Some signs your baby may be ready include:

• Sitting upright independently

• Showing interest in what you're eating and drinking

• Reaching for cups or water bottles

• Drinking confidently from a spoon or taking sips of water with meals

The earlier cups are introduced, the more familiar they become, making the eventual transition much smoother.

Sippy Cup, Straw Cup or Open Cup?

With so many options available, it's easy to feel overwhelmed. Here's a simple breakdown.

Sippy Cups

Sippy cups have a spout that feels somewhat similar to a bottle teat, making them a familiar stepping stone for some babies.

Pros:

• Easy for babies to learn

• Less mess

• Great for on-the-go use

Cons:

• Some children become reliant on them

• May not encourage mature drinking skills as effectively as straw or open cups

Straw Cups

Straw cups are becoming increasingly popular and are often recommended by feeding specialists.

Pros:

• Supports oral motor development

• Encourages mature drinking patterns

• Easy to use once mastered

Cons:

• Some babies need a little practice

• Can be messy during the learning stage

Open Cups

Open cups can be introduced surprisingly early, often from around 6 months.

Pros:

• Supports natural drinking skills

• Encourages coordination

• No specialised equipment required

• Easiest to clean

Cons:

• Messier at first

• Requires supervision

Many families find a combination works best: an open cup at home and a straw cup when out and about.

How to Make the Transition Easier

The key is to make it gradual.

Start by offering small amounts of water in a cup during meals. This gives your baby an opportunity to practise without pressure.

Other helpful tips include:

• Offer the cup when your baby is happy and relaxed

• Let them explore and play with the cup

• Demonstrate drinking yourself

• Be consistent and offer it daily

• Expect spills and mess as part of the learning process

Some babies take to cups immediately, while others need a few weeks of practice.

Common Mistakes to Avoid

• Waiting Too Long

The longer a child relies exclusively on bottles, the harder the transition can become.

• Offering Juice or sweeteners

Water is the best option when learning to use a cup. Juice can increase the risk of tooth decay and may make water less appealing.

• Giving Up Too Soon

Many babies need repeated exposure before they feel confident. Consistency usually pays off.

• Focusing on Perfection

Spills are normal. Learning to drink independently is a skill that develops over time.

A Note for New Zealand Parents

If you're unsure about your child's feeding development, your Plunket nurse, GP or healthcare provider can offer personalised advice. Every child develops at their own pace, and feeding milestones are rarely one-size-fits-all.
