Why Pick a Stainless Steel Sippy Cup For Your Toddler?

Toxic Chemicals Lurking In Sippy Cups

You’d think that plastic sippy cups wouldn’t contain nearly as many chemicals and heavy metals as regular bottles. But, sadly, this isn’t the case.

Substances like bisphenol A (BPA) can leach into the water and force our little ones to come in contact with endocrine-disrupting chemicals.

So what about a BPA-free traditional sippy cup? Well, those come with risks as well. A lot of companies have replaced BPA with BPS.

This under-the-radar chemical is known for its inability to biodegrade, which basically means that “once it is absorbed into the human body it may stay for a longer period of time,” experts say. 

Plastic Pollution 

Let’s not forget that U.S. landfills are overflowing with more than 2 million tons of discarded water bottles as we speak!

In fact, More than 700 species, including sea turtles, fish, and whales, eat plastic or get tangled up in plastic waste — regular cup options are no exception. ‘

Now, if you consider the huge amount of fossil fuels that come along with plastic bottles, the right option is pretty evident. By choosing stainless steel sippy cup alternatives, you can rest assured knowing that it won’t end up in a landfill somewhere for up to 1,000 years. 

What Are The Benefits Of Using Stainless Steel Sippy Cups?

Unlike their plastic counterparts, the best stainless steel sippy cup options are far more healthy and durable.

Also known as the world’s first ‘rustless steel’, stainless steel is extremely corrosion, heat, and fire resistant.

On top of that, because it is so easy to clean and sanitize, stainless steel water bottles and cups are very hygienic. 

Plus, stainless steel doesn’t contain harmful heavy metals such as lead, mercury, cadmium, or arsenic that are known for leaching into the water, food, etc.

 Moreover, it’s 100% recyclable and doesn’t need to go through rigorous manufacturing stages. This means that less fuel is consumed in the process of making the best sippy cups.

How To Pick the Right Stainless Steel Sippy Cup

Now that you know why opting for stainless steel baby bottles is the best option for your kids’ health and safety, let’s get into the trickier part: choosing the best toddler cups.

Consider the spout:

There are 4 main sprout options to consider:

  • The straw cup: These sippies are known for encouraging sucking rather than sipping, however, they do promote a more mature pattern of swallowing that will eventually help your kid to safely drink and eat.
  • Spouts: Cups with a soft spout or a hard spout (aka a tube projecting from the container) mimic the shape of the nipple, which helps kids do the initial transition. Nonetheless, hard spouts can affect your baby’s swallowing habits, speech development, and teeth. So it would be best to stick with a soft sprout just to be safe.
  • 360-lid: The spill-proof, 360-lid option is an ideal trainer cup if you want to encourage the child to sip much like they would from a regular cup. They don’t have a spout or a straw, meaning that the liquid will flow from all angles.
  • Open cups: Open cups encourage proper swallowing patterns and correct sipping action (rather than sucking). Plus, they are great for helping babies build the muscles in their mouths.

Double Walled Insulation

When choosing the best stainless steel sippy cup for babies, moms should always go with double-walled insulation options.

These containers have two layers, specifically created to keep drinks cold or warm for longer periods. 

Handle or No Handle Options

Handles definitely help little hands grab onto the cups a whole lot easier, but if the kid has already developed their motor skills, it would be best to opt for cups with no handles instead.

For very young children, however, the process of holding, lifting, and tipping a cup with two handles can be very beneficial.


It goes without saying that your new toddler cups have to be dishwasher-safe and able to cope with high temperatures.

This way, you can be sure that the cups are fully washed and sanitized before every use.

What does “sippy cup” mean?

The term “sippy cup” refers to a small cup  with a lid and a spout designed to help little ones learn how to sip liquid from the cup without spilling it as they transition from breastfeeding. 

Why do speech therapists not recommend the traditional sippy cup anymore?

Many studies have found that children with prolonged bottle feeding (aka past 15 months), may require to attend speech therapy to address the immature speech patterns that develop.

This is because sippy cups encourage an unnatural, forward positioning of the tongue. The same issue can also cause delayed development of swallowing skills. 

Additionally, many kids with prolonged sippy cup usage have outwards-grown teeth. Don’t fret!

While traditional sippy cups are not the best option anymore, there are plenty of other alternatives to keep your little ones safe and happy during the transitional stage.

Stainless Steel Sippy Cup FAQ

Is stainless steel safe?

Stainless steel is extremely safe for our health and for the environment.

Aside from being a top-quality and durable metal, it is also recyclable and emits no toxins when it comes in contact with liquids.

This means that it doesn’t cause any inhalation, or ingestion issues — unlike plastic. 

What makes a cup preferable for mouth and jaw development?

Open cups are preferred by specialists because they “force” kids to use every part of the mouth which can strengthen mouth muscles.

Straw cups are also great for oral development and cheek muscle strengthening because kids use the same muscles for sipping and food consumption.

Plus the use of a straw cup can also help prevent lisps and slurred speech.  

Are traditional sippy cups still recommended?

The American Academy of Pediatrics recommends children be weaned from the sippy cup by age 2.

Traditional sippy cups are not recommended, because using sippy cups for too long can cause tongue thrust.

That’s why using a straw at 9 months old is a great alternative because it can help to build lip, cheek, and tongue strength and will promote an appropriate resting position of the tongue.

What should I avoid?

Munchkin 360 and the 360-style lids should be avoided because they may cause your child’s tongue to rest in the front of their mouth. So if you are already using a 360 cup, try switching it to an open or straw cup.

In Summary:

Finding the best stainless steel sippy cup for you child can feel overwhelming because there are so many options.

Start with where you plan to use it. If at home, you can likely go with an open cup. If it is for travel, you probably want something with a lid of some sort. After that, pick your size and features. Do you need a handle, for example? And finally, pick your color!
