Best stainless steel sippy cups for babies and toddlers.
Sometimes we forget that the little humans we care for are actually that…little people with their own opinions likes and dislikes. One area toddlers want their voice heard is when it comes to their drinks. Not only do many toddlers get attached to their sippy cups, but they can also be very vocal about the temperature of their beverages.
That’s why choosing a sippy cup can be strangely overwhelming. Not only do we have to worry about the likes and dislikes of our child, but as parents we have to consider the products’ material, design and safety.
And the choices! Plastic or stainless steel, sippy or straw, big or little, insulated or not…there are hundreds of different sippy cups to choose from.
Stainless steel sippy cups are the answer to many parents’ worries about sippy cup safety. They are increasing in popularity and availability as we learn more about how even BPA-free plastics may not be as safe as we had hoped. Not only can you count on stainless steel sippy cups to keep harmful chemicals out of your baby’s drinks, but they are also unbreakable, long-lasting and often insulated to keep drinks the perfect temperature.
We’ve researched and decided on the top 10 Stainless Steel Sippy Cups that will keep your babies and toddlers happy and help you feel good about keeping them safe.

If you’re just looking for the best stainless steel sippy cup to buy, our favorites are:
- for younger babies – L.A. Baby Ultimate Stainless Steel Sippy Cup
- for older babies (who can manage a straw) – the Munchkin Cool Cat Stainless Steel Straw Cup

1) Munchkin Miracle Stainless Steel 360 Sippy Cup

The Munchkin Miracle Stainless Steel 360 Sippy Cup holds 10 ounces of liquid and is insulated to keep drinks warm or cold. This sippy cup has a “miracle” lid (no straw or sippy) which allows for kids to practice drinking out of a real cup without spills or leaking. It comes in four colors and is top-rack dishwasher safe. This sippy cup does not have handles, which gives it more of a “grown-up” look but the design may be more difficult for tinier hands. Some reviewers report that the silicone top begins to deteriorate after several months.
Pros
- holds 10 ounces
- insulated so you can keep drinks cold or warm
- miracle lid helps prevent spills
- dishwasher safe
Cons
- no handles on this one, so might be better for older babies

2) Munchkin Cool Cat Stainless Steel Straw Cup

The Munchkin Cool Cat Stainless Steel Straw Cup has easy-grip handles and is dishwasher safe. This type of cup is recommended by Munchkin for ages 18-months and up, presumably because straws can be tricky for babies to drink from. A sealing ring, when properly aligned, promises a “leak-proof seal.”
Pros

What Is A Stainless Steel Sippy Cup And Why You Need One
A stainless steel sippy cup is a sippy cup made of durable stainless steel instead of plastic. Most stainless steel sippy cups have silicone spouts or straws to drink from. If you are concerned about reducing your child’s exposure to the chemicals in plastic and/or want to keep their drinks warm or cold, a stainless steel sippy cup is a great purchase.
The Different Types of Stainless Steel Sippy Cups
There are several different types of stainless steel sippy cups that are a good fit for different ages.
- Stainless Steel Cup with Sippy Lid: This is the best type of stainless steel cup to purchase as you transition your baby from bottle or breast to sippy cup. This type of lid most closely mimics a bottle or breast and is easier for younger babies (6 months-18 months) to drink from.
- Stainless Steel Cup with Straw: This type of stainless steel cup is a great fit for kids older than 18-months. Designed to look more like a “grown-up” drink container, your little one will love pushing buttons for a flip-top lid (maybe too much!) and will be less likely to turn the cup upside down just to watch its contents leak out. Straws also help prevent contact tooth decay since the liquids go down the throat more quickly and aren’t pushed up against the teeth (like they are with a sippy cup).
- Stainless Steel Cup with “Miracle Lid:” A miracle lid doesn’t have a straw or sippy and is designed to help your child learn how to drink from a cup (without the mess that comes from an open container). Some parents choose to transition their child straight from breast or bottle to a miracle lid cup, but some babies are resistant to losing the comfort that comes from sucking.
4 Benefits Of Using A Stainless Steel Sippy Cup
- Free from harmful chemicals that could leach into your child’s drink
- Double-walled stainless steel provides insulation to keep drinks cold or warm
- More durable than plastic
- Doesn’t absorb smells
- Easier to keep clean
4 Things To Look For In A Good Stainless Steel Sippy Cup
There are several different types of features to consider when purchasing a Stainless Steel Sippy Cup.
- Single-wall or Double-Wall Stainless Steel: While single-walled stainless steel is lighter and easier for babies to hold, it does NOT provide insulation like a double-wall stainless steel sippy cup. If you have a child who is particular about the temperature of their drink and/or spend a lot of time in the car or traveling, a double-wall stainless steel sippy cup may be your best choice.
- Sippy, straw or miracle lid: Consider the type of lid that your baby needs to drink from. Younger babies will do best with a sippy or miracle lid. Older kids will love a straw lid on their stainless steel sippy cup.
- Handle or no Handle: If your child is younger and/or still using their sippy cup at bed and naptime you might want to consider choosing a stainless steel sippy cup that has handles. As they get older you can remove the handles, but having that option might be preferable to a sippy cup that is more difficult to hold.
- Is the model compatible with other types of lids? Some brands of stainless steel sippy cups including Pura Kiki, Thermos Foogo and L.A. Baby have interchangeable lids or tops. This means you can keep using the bottle but change out the silicone tops as your child grows. These brands might also be a good choice if you aren’t sure which type of lid (straw or sippy) will work best for your baby.
In Summary
A Stainless Steel Sippy Cup is a wonderful choice for parents concerned about the dangers of plastic sippy cups. It is also a better choice for kids who are very particular about how warm or cold their beverage of choice is. The durability and variety of options available for stainless steel sippy cups make it an easy choice for parents trying to decide between a plastic sippy cup and a stainless steel sippy cup.
Our favorite choice is the double walled, insulated Munchkin Cool Cat Stainless Steel Straw Cup for older babies (who can manage a straw) or the L.A. Baby Ultimate Stainless Steel Sippy Cup for a sippy spout for a younger baby.
