This kit includes two soft sippy spouts made from medical-grade silicone and a set of easy-to-hold handles, all designed to fit Thinkbaby's 5oz and 9oz bottles. Free from harmful chemicals, it ensures a worry-free feeding experience. ## Description Product Description The Thinkbaby feeding system is a transformational line of products that is meant to follow your child from newborn to toddler and up. This conversion kit turns our Thinkbaby baby bottle into our award-winning Sippy! The convenient handles are made of polypropylene, and encourage motor skill development in your little ones. The spouts are extra-soft, medical grade silicone. Reduces environmental waste by adapting to your child's growth, rather than requiring an all-new bottle when they outgrow bottle feeding. Dishwasher safe, top rack recommended. From the Manufacturer Thinkbaby products address the growing concern of toxic chemicals leaching from consumer products. All products are free of bisphenol-A (BPA), lead, PVC, phthalates, melamine, nitrosamines, and biologically toxic chemicals. The Slow Flow Cross Cut nipples feature our anti-colic system, which helps reduce gas and spit up. The anti-colic system is actually built into the nipple for easy cleaning with no little parts to lose or break. The Slow Flow Cross Cut nipples are designed for newborns to 3 months. If your child is between 3 and 6 months, we recommend our Medium Flow Cross Cut. For ages 6 to 12 months, we recommend our Fast Flow Cross Cut nipples. The advantage to the cross cut design is that is no spill. For extra strong feeders, we do also offer Single Hole nipples. The nipples are dishwasher safe (top rack recommended). One of the great cost-saving and eco-friendly advantages of the Thinkbaby line is that you can extend the life of the baby bottle by simply purchasing the Conversion kit. The Conversion kit transforms the baby bottle into our award winning Sippy cup. For parents this means, no more throwing away baby bottles after one year and for the environment no excess waste. Most little ones become ready for the transition between 9 and 12 months. Check out our top selling Complete BPA Free Feeding Set. Thinkbaby's products are recommended by Healthy Child Healthy World. ## Features - Free of BPA, phthalates, nitrosamines, lead, PVC, PET, and biologically harmful chemicals - Conversion/replacement kit comes with two sippy spouts and one set of easy to hold handles - Sippy spouts are extra soft, medical grade silicone - Designed to fit all Thinkbaby 5oz and 9oz bottles - Handles are made of safe polypropylene ## Images ![ThinkbabyBaby Bottle to Sippy Conversion Kit, Orange - Image 1](https://m.media-amazon.com/images/I/41TVroRblqL.jpg) ![ThinkbabyBaby Bottle to Sippy Conversion Kit, Orange - Image 2](https://m.media-amazon.com/images/I/31ZPolcwntL.jpg) ![ThinkbabyBaby Bottle to Sippy Conversion Kit, Orange - Image 3](https://m.media-amazon.com/images/I/31jvhP+KeuL.jpg) ![ThinkbabyBaby Bottle to Sippy Conversion Kit, Orange - Image 4](https://m.media-amazon.com/images/I/51nB5yxYD+L.jpg) ![ThinkbabyBaby Bottle to Sippy Conversion Kit, Orange - Image 5](https://m.media-amazon.com/images/I/51zV-CgK-1L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐ Good trainer, but could be better yet *by J***R on Reviewed in the United States πŸ‡ΊπŸ‡Έ on February 6, 2010* Okay, so this is the FIRST and ONLY trainer cup that my 10.5 month old son will actually take expressed milk or formula from-- we have been through more types of sippy and straw cups than I care to count at this point (over 15). Despite my excitement about this, I will attempt to not let it taint my review.To give this product a fair appraisal, I must mention that the spouts are VERY much like a bottle nipple. This could be the primary reason for my son's immediate acceptance. We are moving in the right direction, so I don't take *too* much issue with it, but I wish there was another "stage" spout yet, so in the near future I could possibly "graduate" my son to a "real" sippy cup (firmer spout). If you have ever tried Nubys, the "spout" is almost identical in feel/composition, but the shape is a big departure (my son didn't like the Nuby products)-- the closest thing I could compare to in shape is the Born Free trainer spouts (again, no success with those for milk).Now, if like me, you are a self-professed sippy cup expert, to the point of drinking out of one yourself all day to model the "correct" behavior, the baby in you will appreciate that there is no great effort necessary to get the liquid from the bottle. The adult in you will also appreciate that they are almost leak-proof. When tipped on their side or almost upside down, I found a VERY minor drippage; maybe one drop/20 seconds. Yes, I'm very analytical about sippy cups. They go together very easily-- no rocket science here with a million parts or lining things up-- so simple, even a husband can do it ;0) To my disappointment, the spout/nipple frequently collapses when my son is drinking. I have noticed several other people describe the same thing-- I think this is the price you pay for fewer parts-- my son doesn't seem to mind *too* much, so I am more than willing to live with it. I should also note that before purchasing ([...]-- less expensive for bottles), I wrote to the company with questions and did not receive a reply until 6 days later-- too long by my standards, and coincidentally? about the same exact time this review appeared on Amazon (I am presently editing to reflect that I did indeed receive a reply). :(The bottle cap "squishes" the spout/nipple on the conversion kit-- does not seem to affect their present function, but possibly in the long-term? Also note that it seems these parts are compatible with my Born Free bottles-- we have only used them that way a handful of times, but we did not experience any leaking issues (but the inner BF workings are necessary for tight fit). Note that I bought this conversion kit AND a separate set of Thinkbaby bottles, because the "complete" sippy costs a small fortune from merchants who have it in stock at this writing (2/10). I have since ordered more from Amazon, based on the shipping vs. total cost tradeoff. Although this is the first sippy that my son has really taken to, I can only give it 4 stars.Now on to the abbreviated list of good and bad.PRO:LightweightEasy to cleanFew parts (it doesn't get much more basic-- I like that)VIRTUALLY leak-proofSimilar to bottle nipple (also in my list of cons)Easy flowAttractive designCON:MINOR drips/leakageSimilar to bottle nipple (I'd like to have my son use a "real" sippy in the near future)Collapsing spoutCap "squishes" spout when secured on for travel ### ⭐⭐⭐⭐ love the options of conversion *by K***. on Reviewed in the United States πŸ‡ΊπŸ‡Έ on May 10, 2013* As a preliminary review, I love this because I acquired a bottle from a friend, and when looking for transitions from bottles, was happy to find out I could add to what I had rather than buy more gear. That being said, we haven't used it yet and are finding that we may be able to skip sippies altogether because my daughter has taken to rim drinking really well, although messily so far. I've got this around for those times when maybe a mess is not okay (we've yet to find these times, though daycare has been somewhat resistant to rim drinking with the short term mess management). It stinks that conversion kits frequently cost as much or more than similar full new sippy items, but I'm still happy to seek them out, have less stuff around, promote this sustainable design choice. I also recently bought Thinkbaby's Bottle to Straw top conversion kit, which was even harder to find and receive from obscure seller, but similarly, I'm happy to choose that option as needed. ### ⭐⭐⭐⭐ Very good transition *by L***0 on Reviewed in the United States πŸ‡ΊπŸ‡Έ on October 20, 2014* Great transition as your child can keep their "bottle" while still transitioning to a sippy in comfort. The handle is very nice and made my daughter feel like a big kid. The sippy "nipple" is soft an flexible like the regular think baby nipple so its an easier transition once they get over the shape difference. Worked well for my daughter. She went from these to non bottle looking sippy cup no problem. My son had a cleft and sucking issue and these conversion 'Nipples' were not good for him just as an aside. He did not like them. I still think for a straight forward eating baby they are great though. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/1486625-thinkbabybaby-bottle-to-sippy-conversion-kit-orange](https://www.desertcart.pl/products/1486625-thinkbabybaby-bottle-to-sippy-conversion-kit-orange) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-26*
