Comotomo Sippy Cup Conversion

Comotomo Sippy Cup

Comotomo bottles to sippy cup conversion.

Keep using those Comotomo bottles by converting them into a Comotomo sippy cup and even a straw cup.

Here is the step by step process!


How to make a Comotomo Sippy Cup:


Take your clean Comotomo bottle, either size (5 or 8oz) will work.


Unscrew the lid and remove the Comotomo nipple from the bottle.


Replace the nipple with THIS new spout nipple.


Now you have the option of inserting the tube into the end of the new sippy spout nipple. You do this by gently working its ways into the bottom of the sippy spout.  If you use this option, it will act as a straw and your baby/toddler can suck on the spout without having to hold the bottle at an angle.


You can also use the awesome bottle handles that are included in the KIT.

Comotomo Baby Bottle to Sippy Cup


  • Super easy way to keep using your bottles.  
  • If you only use the sippy spout it will be easy to clean . 
  • The kit does include the handles which is a nice feature.
  • Snug fit provided zero leaking when tested.


  • The sippy and straw kit are a little pricey.
  • The straw converter piece moves around in the bottle, so if your child tips the cup up and tries to suck the liquid out nothing may come out depending on the position of the straw tube.   **Keep in mind you don't have to use the straw tube, you can just use the sippy spout.**
  • Not made by Comotomo.


This adapter kit is a great way to keep using your bottles.

Plus your baby already is familiar with the look, feel and shape of the Comotomo bottles, which can make transitioning to this sippy even easier.

Not Plastic Sippy Cups, Our Top 5 Picks

top 5 not plastic sippy cups

Finding the best not plastic sippy cup for your baby is a daunting task.  We will focus on buying considerations and share our Top 5 Not Plastic Sippy Cup  picks.

Things to consider when purchasing a sippy cup:


What material is the sippy cup made of?

Choices will include, plastic, glass, stainless steel, silicone, and biopolymer.


Biopolymer is an environmentally friendly alternative to plastic made from items such as corn or rice husks.

While plastic has its place we try to avoid having plastic touch our babies food and drink.  Plastic leeches chemicals (you may have heard of BPA/BPS).

We are still discovering the nasty ill effects that chemicals in plastics (for that matter chemicals in general) have on our health.

While it is difficult to find sippies and bottles that work well with zero plastic components the key is limiting the amount of plastic that touches your child’s food and drink.


Soft or hard spout sippy cup?  

Soft spout sippy cups usually make for an easier transition from bottle or breast.  They usually have a silicone nipple that is shaped like a sippy spout instead of a teat.  

Hard spout sippy cups are more durable and sometimes come with a flip-top or easy to close option.


Handles or No Handles?  

Babies love to grip things and sippy cups designed with handles are perfect for babies little hands.  

Many brands have handles that can easily be removed so that your baby can use the cup with or without handles.


Easy to clean sippy cups.

You probably have seen the gross photos in the news or social media showing bacteria and mold growth on the inside valve area of certain brands of sippy cups.  

We recommend looking for sippy cups with a simple design that are easy to take apart, wash and reassemble.


Should a sippy cup be leak proof?  

In a perfect world, every sippy cup would be 100% leak proof and spill-proof, making our lives as parents just a little easier.  

Here is the thing, all sippy will leak a little.  Actually you would not want a sippy that your baby has to suck on with all their might.

Cups that are overly difficult to suck from can lead to developmental problems and ear infections due to the softness of babies’ palettes.

TOP 5 Not Plastic Sippy Cups

This sippy cup has it all! 

The main part of the cup is made from vacuum-sealed 18/8 stainless steel.  Stainless steel is a great alternative to plastic.  

This cup is durable and lightweight making it easy for older babies and toddlers to hold. It is insulated makes it a good choice for keeping drinks cold or if your little one prefers milk on the warmer side.  

The Munchkin Miracle cup is also spill-proof. When your child is finished drinking it creates a leak-proof seal.  The sippy cup is valve free, which means your child does not need to suck to get the fluids out of the cup, a preferred option of dentists.

In addition to the stainless steel cup there is a small plastic component that twists onto the cup (the leak-proof piece) and a silicone-like disk that is placed on top of the plastic component.

Replacement pieces for the Munchkin Miracle Sippy Cup are readily available as it is the same pieces used for the plastic version of this cup.

DIY: How to Make a Glass Sippy Cup

how to make a sippy cup dyi

DIY-glass-sippy-cupIn this DIY Mommy Hack, we’ll show you how to turn your mason jars into a glass sippy cup. Glass sippy cups are often hard to find and pricey, ranging from $12 to $19 per cup. Our mason jar sippy cup will range in price from $3 to $10 depending on the size of the mason jar.  Let’s get started!

*Last month we walked you through how to make your own glass baby bottle, you can check that out here.


  • Glass mason jars regular neck 12, 8 or 4oz.   Use regular neck mason jars only, the spout will not work with the wide neck mason jars. We recommend the 4oz or 8oz for younger children as glass is on the heavier side and it will be easier for them to hold.
  • The screw-on rings provided with regular neck mason jarsMason-Jar-Sippy-cup
  • This Nuby silicone spout:  Be sure to use this spout. Nuby makes many different bottle spouts and this is the only one that will work.  Trust us, we have tried others.


Place the Nuby spout inside of the ring provided with the mason jar and screw the ring onto the mason jar.


In a rush and just want to buy a ready-made mason jar sippy cup?  Check this out!

Above is the JellyJackets Silicone Mason Jar Sippy!  You can use the silicone screw-on cap with any regular neck mason jar, the same goes for the silicone sleeve.  Here is a Amazon Link to purchase.


If you are looking for a hard spout glass sippy instead of a soft spout like the Nuby spout listed above, here are some options.

Ball Sip and Straw Lidsball sip and straw lids  These are little plastic disks that sit inside the ring of the mason jar. The hole can be used to sip from or use the straws to create a glass straw cup.

ILidsIlids-Sippy-cup-lids   ILids are neat because the top opening can be sealed shut when you are not using the sippy. *ILids are wide mouth so you will need to purchase wide mouth mason jars.

Cuppowcuppow-mason-jar-lids  These are plastic inserts that sit inside the ring of your mason jar.



Glass Guardianmason-jar-bottle-sleeve is a family based veteran owned business that makes high quality silicone bottle covers right here in the USA.  The best part is that these covers fit onto most 8oz mason jars.  What we love is that unlike some other brands that just wrap around the sides of the mason jar, these fully cover the bottom of the mason jar as well.  Plus there are little raised circular bumps on the covers which helps improve the grip for little hands.

As with all glass products we recommend only using them with adult supervision.

Top 5 Not Plastic Straw Kids Cups

The Best Not Plastic Straw Bottles

TOP 5 Non-PlasticStraw Cups-680Recently several moms have contacted us for recommendations of not plastic straw kids cups.  Here are our Top 5 Picks. Straw cups are a good choice for older toddlers and school-age children, often they are leak-resistant and hold quite a bit of liquid.

Here’s what we are looking for:

  • contains zero or very few plastic components
  • easy for kids to use
  • leak proof (we know this is important for children in daycare or schools)
  • easy to clean; while all the cups we have listed are dishwasher safe, we highly recommend cleaning the straw portion with a brush similar to this one.

Top 5 Not Plastic Straw Kids Cups

Thermos Funtainerstraw-funtainer – Best Leak Proof Option

The Funtainer is a 12 oz insulated 18/8 stainless steel straw cup.  The top part of the straw that kids drink out of is made of silicone and the bottom part is made of a firmer plastic.  My daughter used this cup from K to 3rd grade here in Arizona and even after a long hot day there would still be ice in it.  It has a super easy push button for kids to open and the lid simply needs to be pushed down for the cup not to leak when inside lunch boxes or backpacks.  Dishwasher safe.


straw-foogoFoogo– Best Leak Proof Option for Younger Toddlers.

Perfect for toddlers the Foogo is a smaller version of the Funtainer (above) and holds 10oz. it is recommended for ages 18 months and up.


Pura Kiki Straw Cupstraw-pura – Best Zero Plastic Option

The Pura line contains zero plastic components, it is an 18/8 stainless steel non-insulated cup with a silicone straw system.  It comes with a silicone cap that you can fit over the straw, but this may not be easy for most small children to accomplish.  This would be a great option for  home where the cup would not be transported in a backpack and possibly leak.  The cup is easy to clean and recommend for ages 3 months to 4 years.


straw-bottle-jabricsJabricks Kids Straw Bottle – Cutest, Insulated and Leak Proof

Here is a insulated stainless steel straw bottle with a cute fun design that does not leak when closed.  It holds a little over 9 oz. and has handles, which is a plus.  It is dishwasher safe and has a plastic straw.  Their Amazon product information states it is made from FDA-approved and BPA-free materials.


Buggygear Glass Straw Bottlestraw-buggygear – Best Glass Straw Bottle

This is a 14oz glass insert that fits inside a plastic shell, similar to, but larger than the Green Sprouts Sip n Straw cup.  The borosilicate glass is stronger than regular glass and helps protect against breakage.  The straw is silicone and the cup is dishwasher safe.  Recommended for 18 months and up and for supervised home use because after all, glass can break.

Pura Kiki Stainless Steel Baby and Sippy Bottles

Bottles that grow with your baby Pura

The Pura alternative to Plastic baby bottles and sippy cups.

The stainless steel Pura baby bottles and sippy cups are a great alternative to plastic.  If you have decided to stay clear of any plastic baby and sippy bottles, and now you are on the hunt for a stainless steel baby bottle that can also be used as a sippy cup, Pura baby bottles are the bottle you have been looking for.

In general, I tend to lead parents to a hybrid style bottle that will grow with their child. In other words, a baby bottle that can then easily also be used as a sippy bottle. For glass, I usually steer parents to the Lifefactory glass bottles (I will write more about Lifefactory soon). And for a stainless steel hybrid bottle, Pura is the way to go.

Pura designed their line of baby and toddler bottles with a few simple concepts in mind featuring:

  • no plastic components
  • a versatile style opening that allows you to choose from a large selection of nipples and sippy spouts that are compatible with the bottle

Why is this so important? Can’t I just buy the Pura brand of nipples?

Yes, you can, but as a lot of parents find out over time, your baby or toddler may tend to prefer a brand of nipple or sippy spouts over another. So instead of having to spend your money and time looking for a perfect fit, Pura makes it easy.

Pura bottles come in either a 5oz. or 11oz baby bottle size or an 11oz. sippy size. There are even some fun sealing disks that can turn the bottle into a great storage container for snacks while on the go. Below is a chart of all of the nipple and sippy tops that are compatible with the Pura bottles.
