Can you put a smoothie in a sippy cup?

Quick Answer

Yes, you can put a smoothie in a sippy cup. Sippy cups are designed to prevent spills, so they can be a useful vessel for containing blended smoothies. The lid and spout on a sippy cup allow you to drink a smoothie without worrying about it splattering or spilling. Just be aware that some ingredients like yogurt or ice may clog the spout. Blending the smoothie well and straining it can help avoid clogs.

Exploring the Possibilities of Sippy Cup Smoothies

Smoothies make a delicious and nutritious drink for people of all ages. Babies, toddlers, kids, teens, and adults can all benefit from smoothies’ blend of fruits, vegetables, dairy, protein, and other healthy ingredients. However, traditional open cups and glasses can lead to messy spills when drinking a smoothie. This is especially true for babies and young toddlers who are still developing their fine motor skills. An innovative solution is to serve smoothies in sippy cups, which are designed for spill-free sipping.

Sippy cups have been around since the 1950s and originally were created as a transition cup for toddlers learning to drink from an open cup. They have a lid with a spout that minimizes spilling and allows drinking while tilted. These days, sippy cups come in many shapes, sizes, and designs. Some are aimed at babies 6 months and up, while others are marketed for older toddlers and pre-schoolers. The key features that make them effective smoothie vessels are their anti-spill lids and spouts.

Let’s explore the benefits and possible concerns of putting smoothies in sippy cups for babies, toddlers, and older kids:

Benefits of Sippy Cup Smoothies

– Prevent messes: Sippy cups allow smoothies to be enjoyed spill-free, avoiding the splatters of open cup drinking. Babies can hold and sip independently.

– Promote independence: Sippy cups with smoothies enable babies and young toddlers to self-feed the healthy drink. This builds confidence and coordination.

– Control portion sizes: The set volume of a sippy cup makes it easy to monitor how much smoothie a child consumes. This prevents overfeeding.

– Make smoothies portable: Sippy cups with lids allow smoothies to be taken on-the-go and drank in strollers, cars, etc. Open cups would spill in transit.

– Fun colors/designs appeal to kids: You can find sippy cups in fun shapes, colors, and designs that make kids excited to drink their smoothies. Appealing to their interests promotes healthy habits.

– Easy transition to open cups: Sippy cup use can be an intermediate step to teach older toddlers and pre-schoolers to drink from open cups without spilling.

Potential Concerns

– Difficulty cleaning: Sippy cup spouts and valves require special cleaning brushes to thoroughly clean out remaining smoothie residues. Improper cleaning could allow mold and bacteria to grow.

– Spout clogging: Ingredients like yogurt, oats, seeds, peanut butter, etc. may clog the sippy cup spout. Blending smoothies very smooth and straining can help avoid clogs.

– Over-reliance on sippy cups: Letting children use sippy cups for too long can lead to prolonged reliance on spouted cups instead of transitioning to open cups.

– Tooth decay concerns: Constant sipping and drinking of sugary smoothies throughout the day from a sippy cup increases risk for tooth decay. Limit sippy cup use to mealtimes.

– Choking hazards: Ensure smoothies contain soft, age-appropriate ingredients. Hard chunks could pose a choking risk as they pass through the spout.

Best Practices for Smoothie Sippy Cups

Here are some best practices for safely enjoying smoothies in sippy cups:

– Select a sippy cup designed for the child’s age and developmental stage. Opt for soft silicone spouts for young babies.

– Clean thoroughly after each use with bottle brushes reaching the length of the spout. Sterilize periodically.

– Avoid putting extremely thick or chunky smoothies in sippy cups. Strain ingredients or blend until very smooth.

– Introduce sippy cup use slowly alongside open cups. Use open cups more as kids approach toddler age.

– Limit sippy cup smoothie drinking to mealtimes. Don’t allow constant sipping throughout the day.

– Store freshly made smoothies in an airtight container in the fridge, not sitting for hours in a sippy cup. Discard after 24-48 hours.

– Monitor children closely while consuming any drink from a sippy cup to avoid excessive air intake. Take occasional pauses.

Smoothie Ingredient Considerations for Sippy Cups

The types of ingredients used in smoothies for sippy cups require some special considerations. Some ingredients are better suited for sippy cup smoothies than others based on texture, thickness, and potential to clog the sippy cup spout. Here are some guidelines for selecting ingredients:


Fruits form the base of most smoothies with their natural sweetness and nutrients. Fruits like bananas, berries, pineapple, mango, peach, apple, and melon are all great smoothie ingredients for sippy cups. Be sure to peel, core, and seed fruits as needed. Overly hard unripe fruits may be difficult to blend smooth.


Adding veggies like spinach, kale, carrots, sweet potato, and pumpkin to smoothies boosts nutrition. Cook any hard, fibrous veggies like carrots before blending to soften. Strain blended greens to remove fiber that could clog sippy cup spouts.

Yogurt and KEFIR

Dairy products like yogurt, Greek yogurt, and kefir provide protein, calcium, and probiotics. Choose unsweetened varieties. Thick Greek yogurt strains well but dairy can still potentially clog a spout.


For thinner smoothies, use unsweetened juices like orange, apple, grape, or prune juice. Limit juice to avoid too much natural sugar. Focus more on whole fruits and veggies.

Frozen Fruit

Use frozen bananas, berries, peaches, mango, etc. to create thicker, creamier smoothies. Allow frozen ingredients to thaw slightly before blending.


Ice helps blend and chill smoothies but can pose risks for clogs in sippy cup spouts as it melts and reforms. Use sparingly or avoid altogether by blending with frozen fruit instead.

Seeds, Nuts, Nut Butters

Chia, flax, hemp and pumpkin seeds boost nutrition but should be ground first or strain blended smoothies to remove. Similarly, peanut, almond, or cashew butters add protein but may clog. Use sparingly and blend thoroughly.

Protein Powder

For a protein boost, whey or plant-based protein powders dissolve well but check labels for added sugars. Focus on whole food sources of protein too like yogurt.


Avoid adding sugary syrups, honey, agave, etc. Rely on whole fruits for sweetness instead. A touch of maple syrup is acceptable.

Choosing a Sippy Cup for Smoothies

With so many sippy cup options on the market ranging from bottles to 360 degree cups, narrowing down the best choices for smoothies involves some key considerations:

Spout Type

– Soft spouts are best for young babies’ gums but don’t allow large particles to pass through

– Hard spouts accommodate thicker smoothies but must be soft enough not to hurt gums

– Some allow removable parts for more thorough cleaning

Spout Flow Speed

– Slow-flow spouts are better for smoothies to prevent choking from excessive drinking speed

– Fast-flow better suits water; aim for middle ground flow speed


– Look for one-piece valves without nooks and crannies where smoothie can collect

– Silicon valves tend to be more flexible for thorough cleaning

Cup Size

– Around 6-12 ounces is ideal for portion control

– Select cups sized for child’s age and stage

Ease of Cleaning

– Dishwasher safe parts clean most thoroughly

– Simple designs with fewer parts allow better access for cleaning

– Cleaning brushes to scrub the length of the spout are essential
