Doidy Cup - Your baby's First Trainer Cup
The original free flow, open trainer cup, approved by the NHS.
Designed by Experts, Trusted by Parents & Health Professionals.
Since the Doidy Cup’s development in 1950, The Doidy Cup is tried & trusted in baby weaning and open cup training for over 75 years. Unlike standard sippy cups and bottles, the Doidy Cup’s free-flow, open design supports healthier dental and speech development by removing the need for a suckling motion. Its unique oblique shape allows children to see the liquid level inside, helping them develop early hand-eye coordination and making cup training easier, while also easing the transition from bottle to open cup.
Health Professionals, the Government and leading health organisations such as the BDA recommends the introduction of an open cup at around 6 months of age and completely stopping the use of a bottle by 12 months. As well as teaching valuable skills there are a number of critical health benefits associated with open cups compared to other drinking vessels.
Supporting speech development through proper oral posture.
Drinking from an open cup encourages the correct tongue, jaw, and lip movements needed for clear speech. The Doidy Cup’s open, free-flow design allows babies to drink naturally, promoting proper oral posture essential for speech development. Research suggests that early oral muscle coordination supports clearer pronunciation and more effective communication. Babies who develop strong oral muscles through natural drinking methods also gain confidence in their ability to express themselves, leading to better interaction with parents and caregivers.
Training hand-eye coordination.
Learning to drink independently is an important developmental milestone, and the Doidy Cup is designed to make this process smoother. Its slanted design allows babies to see the liquid inside, helping them gauge how much to tilt the cup and develop better control over their movements. This improves hand-eye coordination and oral-motor skills, both of which are essential for safe and efficient drinking.
By providing visual feedback, the Doidy Cup also helps prevent overfeeding, as babies can better regulate their intake. As they practise these skills early on, they gain confidence in handling their drinks, reducing spills in the future and making the transition to independent drinking and weaning much easier.
Healthier choice for teeth - no teats or spouts.
Sippy cups and bottles with teats encourage prolonged sucking, which can negatively impact dental development. Dentists recommend open, free-flow cups and advise against non-spill designs or sippy cups with valves, as these encourage continued sucking rather than natural sipping. One major concern is baby bottle tooth decay, which occurs when liquids—especially milk or juice—pool around the teeth, increasing the risk of cavities. Decay in baby teeth can lead to further issues with permanent teeth, such as additional cavities and improper tooth placement.
The Doidy Cup eliminates the need for teats and spouts, promoting natural drinking motions rather than sucking. This not only supports healthier oral development but also helps reduce the risk of tooth decay by preventing excessive liquid exposure to teeth. Dentists recommend open, free-flow cups and advise avoiding non-spill designs or sippy cups with valves in them.
Easier transition from breast to cup.
Many parents find that moving from breastfeeding to cup drinking can be challenging, but the Doidy Cup’s carefully designed shape helps ease this transition. Drinking from the Doidy Cup is a natural progression from breast feeding because it uses the same suckling motion, so mothers can make the move from breast to open cup in one step rather than introducing a teat or spout.
The two-handled grip also provides extra stability, giving babies the confidence to hold and control the cup themselves. The sloping design allows a more natural upward and downward motion of the hands and arms (unlike bottles and sippy cups which require forward and backward movement of the head).

Instructions
1. Wash the Doidy Cup before first use.
2. Place a small amount of liquid in the cup, gently hold the cup at the bottom and place the rim on the lower lip to allow baby to take what they want. Make sure you are at the same level as your child.
3. As baby grows, they will want to hold the handles and feed themselves, picking the Doidy Cup up and placing it down independently. Some spillages may occur but this is part of the learning process.

- Keep out of reach of children when not in use.
- Replace cup if there are any signs of wear or damage.
Safety & Warnings
- Adult supervision is required at all times. Never leave a baby unattended while feeding.

- Always check food and drink temperature before feeding.
- Never let children play with the packaging.
- Do not use if there are signs of damage or weakness to either the primary packaging or the product.
When should I introduce the Doidy Cup?
Doidy Cup can be introduced as early as 3 months, depending on your baby’s progress and acceptance of the cup.
The NHS and NCT recommend that parents and caregivers should introduce open cups by 6 months and eliminate bottles by 12 months.
Why does the Doidy Cup have this slanted, oblique design?
The unique angled shape allows babies to see the liquid inside, helping them learn how much to tip the cup, a key part of learning to drink independently. This design supports hand-eye coordination and oral-motor skills, making it easier for babies to transition to independent drinking.
Can you use Doidy Cup instead of a bottle or a sippy cup?
Yes, dentists and health professionals recommend open cups over sippy cups and bottles to support proper oral development and reduce the risk of baby bottle tooth decay. Unlike teats and spouts, which encourage prolonged sucking, the Doidy Cup allows babies to sip naturally, promoting healthier tongue, jaw, and oral muscle development. Many parents even choose to skip bottles, teats, and spouts altogether, moving straight from breastfeeding to the Doidy Cup for a smoother, more natural transition to independent drinking.
How do I minimise spills during training?
With an open cup design, spills are more likely compared to closed cups or those with valves. However, spills are a natural part of the learning process, helping your baby develop better control and coordination while drinking. Unlike closed cups, the Doidy Cup allows babies to see the liquid inside, giving them important visual feedback to adjust their movements.
To minimise spills, we recommend starting with small amounts of liquid and gently guiding the cup as your baby gets used to drinking from it. As they gain confidence, allow them to take more control of the cup and encourage its use during meal times, when they are more focused and seated in an upright position.
How do you clean the cup? Can this be sterilised?
The Doidy Cup is top-shelf dishwasher safe and can be cleaned using a steam or UV steriliser if needed. However, for everyday use, a simple hand wash with warm soapy water is usually sufficient. Regular cleaning helps maintain hygiene while preserving the cup’s durability.
How durable is the Doidy Cup?
The Doidy Cup is made from durable, BPA-free, food-safe polypropylene, a highly trusted plastic material known for its safety and strength. Designed to withstand daily use, it is lightweight for easy handling and is dishwasher safe. It can also be safely cleaned using steam and UV sterilisers, ensuring hygiene and convenience for parents.
Is the Doidy Cup recyclable?
Yes, the Doidy Cup is made from polypropylene (PP) and is fully recyclable. However, we encourage reusing and repurposing the cup before recycling, as it is a durable and versatile household item. Its bright colours and practical shape make it useful beyond mealtimes—it can be repurposed for watering flowers, holding small items like clips, or even as a fun container for arts and crafts supplies. By finding creative ways to reuse the Doidy Cup, you can extend its lifespan while reducing waste.

I like that your baby is not able to spill it. I also like the fact the cups are brightly coloured which is more appealing for babies. I have been told that this cup is better for their teeth than a beaker and is good for their hand eye co-ordination. Hopefully in time once my baby is a bit older she will start holding the cup by herself.

To say this item was life changing sounds like an exaggeration but it’s true!
My baby has refused a bottle since day one but we tried this cup on the recommendation of a friend and it’s brilliant. She drank every drop of expressed milk meaning that I’ve had a lot more freedom and she can now be left for longer periods with her dad or grandparents.
It’s also been great for weaning and teaching her how to sip. She can now drink from any open cup and she’s only six months.
I would give this product six stars if I could! Amazing

Love these. Our 8 month old has been using them since he started weaning. He never took a bottle so we’ve used these for a while. Great product.

I have tried several of the cup and my daughter is still unable to drink without a straw. Only this one is the best for her to learn. And she likes to drink with cup now.

Way better than normal or sipper cups for weaning. You can see how much water is going in mouth and can assist baby with the flow. Baby is already getting better at using it within a couple weeks.
