Best Sippy Cups for Transitioning


To take the guesswork out of choosing a practical and feasible sippy cup for your baby’s transition phase, we have compiled this valuable buyer’s guide and review of the best sippy cups for babies from between 6 months and two years old, for ease of reference.

Our top selection of sippy cups was guided by sage advice and recommendations from dozens of supermoms, pediatric and lactation experts, academic research institutions, and peer-reviewed studies.  

We have also placed great value on online feedback and reviews from customers who bought sippy cups. It makes sense that their babies are the ultimate 'testers’ of the integrity and feasibility of these clever feeding utensils regardless of a brand’s high acclaim in the media.

Why Transition to a Sippy Cup?

The experts agree that although one year is the target age for babies to transition to a sippy cup, they recommend starting earlier according to your baby’s development.  

The reason for favoring an early start is, the longer babies are breast or bottle-fed, the predictability and familiarity can become too comforting and convenient for both baby and mom. 

Toddler and Sippy Cup

The longer you delay in weaning your baby once they reach their first birthday could rob him of developing critical motor, sensory, and cognitive skills that stimulate hand-eye coordination. Sucking and sipping actions coupled with different positioning of the lips and tongue when using sippy cups also aid speech development.

Different Types of Sippy Cup Spouts

Sippy cups come in a variety of shapes, sizes, materials, and price ranges. It can become confusing once you walk into a store or shop online without prior knowledge about what to look for that’s age-appropriate and meets your baby’s developmental needs. 

Let’s firstly focus on the type of spout. Choosing the wrong sippy cup spout can make or break your aspirations of having a smooth transition. It's often necessary to get a few sippy cups and allow your baby to test them and select the one they feel most comfortable with. 

Sippy cup with a soft spout

Dentists recommend these for babies transitioning from 6 months old (and younger). A soft spout feels similar to the breast and a bottle's soft nipple. Some cups come with double handles, and some brands have removable handles, easy to remove if they prove to be awkward for your baby to hold. 

Sippy cup with a hard spout

The hard spout challenges your baby to use different muscles and movements. It helps your baby transition from sucking to sipping and having to tilt his head back a little while lifting the cup. You can immediately see that this requires solid head-and-neck control.

Straw Sippy cups

Some cups come with a weighted straw. Interestingly, some babies at 5-months old have learnt to draw milk up into the straw even though they learn to master this action from 8 or 9 months onwards. Superstars!

It still requires a sucking action, the difference being in the pursed-lip action, the rolling of the tongue, and swallowing. These actions aid oral motor development. It also encourages babies to hold the cup independently.

Spoutless Sippy cups

These cups come with a flat, vacuum-sealed top, popularly called 360-degree cups. They allow the milk to flow from all the edges around the cup, resembling drinking from a standard open cup, although spill-proof. 

Open-top Sippy cup

Once your little one can handle the spoutless sippy cup quite well, it’s the perfect time to transition to an open-top sippy cup. These are slightly smaller than the standard cups in your kitchen but much more break-proof if dropped. 

Remember to put only breast milk, formula, or a little boiled, cooled water in the training cup. Do not use fruit juice in a sippy cup, which is high in sugar and will lead to tooth decay!

So for your convenience, our team of experts have rounded up the best-designed and most practical sippy cups. It will save you valuable time, money, and energy having to search through a myriad of confusing designs and styles.


This spoutless self-sealing sippy cup with its flat 360-degree leak-proof lid is designed with outstanding features that favor seamless transition for breast and bottle-fed babies.

Dentists recommend these as the safest transition cup as it won’t lead to tooth decay due to the sipping action being similar to drinking from an open cup (without spills and mess). It also aids normal muscle development, a big plus.

Buyer’s Guide to Selecting the Best Sippy Cup

Parents need to be mindful of a few things before parting with their money, especially with sippy cups. Firstly, the age of your baby and how independent he or she is in his developmental phase would determine the design and type of sippy cup to buy. 

Tips for selecting a good sippy cup

  • Leak-free and spill-proof: Not all sippy cups are completely leak-proof. Some are spill-proof and leak-resistant, meaning the cup may be weighted to keep its balance, or it has certain features that will minimize spills and messes.
  • Easy for little ones to manage: babies and toddlers are very picky about their likes and dislikes, which parents may never understand. While a five-month-old baby may take to a straw sippy cup, a one-year-old may prefer a soft nipple or spout. Under two years old, handles that make it easy for little hands to grip encourages babies to drink independently.
  • Effective cleaning: It’s a fact that any vessel that holds food or drink becomes a target for residue build-up and breeding ground for germs and mold. Ensure the manufacturer has provided clear instructions on how the sippy cup can be taken apart and how to reassemble it. 
  • Safety of material: The FDA requires that all material used in sippy cups should be free of BPA or any harmful chemicals. However, some parents are cautious about the possibility that unknown chemicals are released from the plastic material. Fortunately, there are alternative options available such as stainless steel, silicone, and glass, but understandably, they will cost more.
  • Customer reviews:  In these times of digital media, consumers feel they owe it to others to leave a review after their purchase. Most people won’t buy a product unless they have searched through feedback from both happy and unhappy customers, as they also learn about the integrity and professionalism of the company and their customer service.

How to Keep a Sippy Cup Hygienically Clean

  1. Bacteria and mold are the main culprits that accumulate in the hidden crevices if left untreated. Although sippy cups can be dismantled for thorough cleaning and sterilizing, you will still need a few small-sized brushes to reach difficult to reach corners, especially to clean out straws and vents.
  1. After your little one has finished the contents of his sippy cup, rinse it immediately with warm soapy water. Alternatively, depending on sticky content, you may need to immerse the cup and soak it for a while to ensure no residue forms in nooks and crannies.
  1. Dismantle the cup according to the manufacturer’s instructions and detach all components that can come apart. If the sippy cup is dishwasher-safe, place the parts carefully in the cutlery or small compartment of the dishwasher. 
  1. Dry all components thoroughly with a soft sterilized cloth before reassembling the sippy cup. Ensure you align the handles (if any) and valves and seals are inserted correctly so that the cup doesn’t leak.
  1. If you wish to sterilize the cup, you can place it in the microwave (if it’s allowed) or submerge the individual parts in boiling water for a few minutes. Dry thoroughly before reassembling them.
  1. If your baby's sippy cup doesn’t have a lid cover, you can do an online search for universal lid covers for straw, nipple, or spout sippy cups.

Key Takeaways

Transitioning from breast or bottle-fed to handling a sippy cup is a significant milestone for your baby. 

We emphasize making the transitioning phase fun and a family affair, especially around the dinner table. With your baby seated in his high chair, he becomes an integral part of the family’s social interactions. 

In this safe, comforting space, provide your little one with every opportunity to practice and hone his social skills and introduce him to his new sippy cup. You may have to try a few different designs until your baby accepts the one he feels comfortable with.

You should always clear up any questions or discuss concerns with your baby’s pediatrician to ensure your baby’s transition is smooth and on par with his growth and development.
