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: Happy mom - Philip agent natural moms this is a must!!! Really great transitional piece for toddler! Toddler had no trouble transitioning and helped with independent feeding. The flow is similar to the nipple. If baby stops feeding it stops with and no over spill. It is easy to attach to nipple lid and easy to remove to clean. The set comes with a brush so helpful for cleaning. We do use it with the 9oz bottle as the straw is longer. Overall 10/10!

### ⭐⭐⭐⭐⭐ 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.
