Review: Get More Use Out of Your Bottles - This straw cup conversion for the Philips Avent bottles is amazing! My 9 month old had been using a honeybear cup that wasn't spill or leak proof, so I was looking for another straw cup solution. We also still had a handful of glass bottles that we weren't using anymore because baby had been refusing bottles for a few months (breastfed). This straw conversion fits and works perfectly on our 4oz bottles! There's an extra amount of straw down in the glass (see photos) because I believe they're intended for the larger bottles, but that hasn't impacted their functionality, especially since they are weighted. Very easy to use - this pops into the bottle screw ring, where you'd normally put a nipple. The handles on the side are easy for baby to grasp and hold on their own. These have a valved straw, so they don't leak. They're are a little annoying to clean, so I wash them in the dishwasher and they've held up well so far. It's been 10 days and I've been washing them once a day. My only real complaint is the price because I feel they are expensive for what they are. But I'm happy to be getting use out of our glass bottles again!
Review: Our go to - We use the glass Philips avent bottles so we got these attachments for cabinet space and they are the only ones our 1 year old will use. They were very easy for him to convert to from the bottle. Easy to clean, have had no issues with leaking, great for minimum space when stored. Plan to purchase more.

## Features

- ✅ Effortless Transition from Baby Bottle to Sippy Cup – Make weaning easy with our sippy conversion kit, designed to fit Philips Avent Natural Baby Bottles and Glass Bottles (any size). No need to buy new cups—just replace the bottle nipple and let your baby transition at their own pace.
- ✅ 100% Safe & Baby-Friendly Materials – Made from BPA-free, phthalates-free, lead-free, and FDA food contact-safe materials. Independently tested to meet U.S. Consumer Product Safety Commission (CPSC) standards, ensuring the highest level of safety for your baby.
- ✅ No Plastic Touches the Drink – Unlike other brands with plastic weighted straws that require disassembling small parts (connector, tube, ball) for thorough cleaning—our all-silicone weighted straw is a single-piece design. No parts to take apart, no risk of losing small pieces, and effortless cleaning. Plus, only soft, food-grade silicone ever touches your baby’s drink, ensuring a safer, healthier drinking experience.
- ✅ Planet-Friendly & Cost-Saving Solution – Reduce waste and save money by reusing your baby bottles instead of purchasing all-new sippy or straw cups or trainer bottles. A sustainable and budget-friendly alternative for smart parents who care about the environment.
- ✅ Spill-Proof, Mess-Free Design – Designed with a weighted any-angle straw, allowing babies to sip comfortably from any position. The leak-resistant spout helps prevent spills, making it perfect for on-the-go use.
- ✅ Easy to Hold & Clean – Comes with ergonomic bottle handles to help little hands grip independently. Includes 2 cleaning brushes for hassle-free cleaning of the straw and spout, keeping everything hygienic for your baby.

### ⭐⭐⭐⭐⭐ Great product!
*by R***E on October 17, 2025*

Honestly i never write reviews on anything unless i feel very strongly one way or another about a product..but these are AMAZING! We were big Philips avent bottle fans during the infant stage, mainly bc they do not leak at all and were convenient to travel with..and these weighted straw conversions for the bottle are so great! The weighted straw works perfectly and does NOT leak like other weighted straw cups I’ve purchased for my baby. The handle is great, as well and fits snuggly. Not sure why we didn’t just invest in these from the beginning when we started the transition from bottle to straw cups. Super convenient since you already have the bottles - no need to spend extra money on different kinds of cups when you already have them. My daughter took to this straw immediately and they are now our go-to cup over any of the other straw cups we have.
