Are you in the market for safe sippy cups and trying to avoid plastic? 

In this post, I’ll go over all of the pros and cons of my three favorite safe sippy cups which include; Green Sprouts Glass Sip & Straw, Klean Kanteen Sippy Cup, and Greens Steel 10oz Stainless Steel cups, and the Boon silicone sippy lids.

Plastics can be hazardous to our health as they can contain harmful chemicals like BPA. It only makes sense to switch to more sustainable and eco-friendly sippy cups!

UPDATE: After using these products for a few more years I’ve updated my review below! 

Why Look For Safe Sippy Cups?

The main reason you may want to look for alternatives to plastic sippy cups are because of the chemicals that can leach into your drink.

Glass and stainless steel are tried and true as far as safety goes, even with their drawbacks.

BPA is one of the bad chemicals you will want to avoid but sadly there are estrogen mimickers found in BPA-free plastics too.

Silicone is a great option because it is soft and non-toxic. There hasn’t been a ton of studies on it yet, so I would like to see more research on its safety.

I genuinely loved the Boon Sippy Lids (Amazon aff link) because they made any cup into a non-spill sippy. However, I found that my oldest would bite the tops off so I had to stop using them.

They also make Boon Straw Lid Toppers, (Amazon aff link) but I never got around to purchasing them.

What About Other Options?

Latex is another good alternative to plastic but some children are allergic to it so it may be harder to find.

Even though stainless steel is one of the safest materials, you will want to be careful not to put too many acidic drinks or heat up the sippy.

If stainless steel is heated, it can leach heavy metals into your drink.

Normally, heating is not an issue. I like to use glass if I’m going to serve juice or warm milk. Each material has its pros and cons which is why I like to have a little variety when choosing what I want to serve.

Klean Kanteen Sippy Cups (Amazon aff link) are perfect for traveling as they fit nicely in your diaper bag and come with a cover. They also can be used for kids if you change the lid out.

These are my personal favorites for traveling. The only problem with these sippy cups are that they are hard and cold when you fill them with a colder drink. 

To get around this, I found some cheap dollar store mugs to put on them.

This also protects the floor if they get dropped. 

When you’re ready to move onto cups, Greens Steel Stainless Cups (Amazon aff link) are great for toddlers, kids, and adults!

They have a sleek and timeless look and you don’t have to worry about them breaking like glass. They also pair really well with the Boon silicone lids. 

We use these a lot. In fact, I need to order some more.

I kind of wished they had a silicone bottom to add extra spill resistance but then they probably wouldn’t stack well.

I like to fill them with my homemade smoothies and sometimes ice cream. 🙂

The Green Sprouts sippy cup is a fantastic training sippy for when baby is first transitioning from a bottle. It also includes a straw option.

However… Because there were so many pieces and attachments to keep up with and wash I no longer recommend these.
