When your baby’s ready to graduate to a toddler straw cup, these convenient silicone straw conversion tops are all you need. Designed to fit perfectly on your 8 ounce Nursh baby bottles, the silicone straw in these lids turns your existing baby bottle into a kids' straw sippy cup. The unique design of the silicone straw combines with your baby bottle’s existing silicone pouch for drinks. This straw is made of 100% silicone, perfect for transitioning from a bottle to a cup, giving your little one the familiarity they need while educating them on drinking from a straw. The rotating cover and valved straw included in this conversion top keeps the drinks inside the cup and off of your kid. This product is perfect for toddlers who are ready to transition from baby bottles or older children using our feeding supplies. What’s that? You only have 4 ounce Nursh bottles? Go ahead, carefully cut the straw down to size, we love a good parenting hack! Review: better for older kids - love the idea of these, i’m a big fan of boon, but since they are more leak proof it is harder to drink through the straw it requires more suck. not a good option for my 10 month old learning to use a straw but keeping it for toddler age. Review: Great next step! - These are great!! Having already had the Boon bottles from my baby registry, these are a perfect upgrade for baby who’s ready to move to sippy cup style! Love that they are a valves straw so no backwash and graduated drinking which allows for baby to not choke on water as they learn. Mostly spill proof though some does leak out of the straw a little but has been dropped on the floor and tipped upside down multiple times and doesn't spill! As an OT mama I love this option in place of a standard sippy cup ## Features - Silicone Sipping: The Nursh conversion top with a silicone straw combines with your NURSH bottle’s silicone pouch for drinks that only touch 100% beverage-safe silicone - Spill Proof Cups: These straw cup lids changes your baby bottle into a no spill sippy cup with a valved straw that creates a spill proof seal to keep drinks in the cup - Flip Top Straw Cup: These Nursh straw cup lids feature a rotating cover that helps keep the straw clean when not in use while keeping their beverages safe from spills while on the go - Easy to Clean: Rest easy knowing that these sippy cup lids are top rack dishwasher safe just like the Boon Nursh silicone shell, ensuring their favorite sippy cups are always ready for a new day - Toddler Cups: These sippy cup lids are for use with Boon Nursh bottles to create a transitional cup for your little one when transitioning from baby bottles to toddler sippy cups with straws ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08ZH9H35L | | Best Sellers Rank | #2,861 in Baby ( See Top 100 in Baby ) #80 in Toddler Cups | | Brand | Boon | | Brand Name | Boon | | Closure Type | Flip Top | | Color | Clear | | Customer Reviews | 4.1 out of 5 stars 2,112 Reviews | | Included Components | 2 Silicone Straw Conversion Tops | | Is the item dishwasher safe? | Yes | | Is the item microwaveable? | Yes | | Item Type Name | Silicone Straw Conversion Top | | Manufacturer | TOMY Intl. | | Material | Silicone | | Material Type | Silicone | | Number of Pieces | 2 | | Product Style | Straw Sippy Cup Lid | | Shape | Round | | Style | Straw Sippy Cup Lid | | UPC | 669028114986 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Boon - **Color:** Clear - **Material:** Silicone - **Shape:** Round - **Style:** Straw Sippy Cup Lid ## Images ![Nursh Silicone Straw Sippy Cup Lid - Conversion Top for Bottles - Toddler Cup Top - Changes Baby Bottles into Cups - 2 Count - Image 1](https://m.media-amazon.com/images/I/61GlBOnUy2L.jpg) ## Questions & Answers **Q: I have the 4 oz bottles, can i just cut the straws to fit or is there another shorter straw conversion set?** A: They don’t make straws for the 4oz bottles since the smaller size is generally used for younger infants. The straws have bite valves at the top so are more suitable for 9months + of age for which a child is usually using a larger bottle. To answer your question - technically you could cut the straw. **Q: Can this fit mason jars ?** A: No, the threads are different. **Q: Is this a direct match for the grey boon nursh?** A: the straw top fits all of the silicon pouch bottles (4 and 8 ounce or all colors). Our daughter loves them and it makes the bottles usable for a lot longer. **Q: Am I wrong Description states 2 pack but was only one in package** A: It should be two ## Customer Reviews ### ⭐⭐⭐⭐⭐ better for older kids *by K***A on April 16, 2025* love the idea of these, i’m a big fan of boon, but since they are more leak proof it is harder to drink through the straw it requires more suck. not a good option for my 10 month old learning to use a straw but keeping it for toddler age. ### ⭐⭐⭐⭐⭐ Great next step! *by E***E on February 6, 2025* These are great!!
