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).

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. ## Frequently Bought Together - Sippy Cup Conversion Kit for Philips Avent Natural Baby Bottles 2-Count Food Grade Silicone Spout Nipples, All Silicone Weighted Straw, Bottle Handles, Cleaning Brush, BPA-Free 4+ months (Sippy Spout) - Philips Avent Natural Glass Baby Bottles with Natural Response Nipples (Medium Flow, Flow 3), 8oz, 4-Pack, SCY913/04 - Juome Silicone Sleeves with Handles for Avent Natural Glass Baby Bottle - 3 Pack Anti Breakage Baby Bottles Holder, Compatible with Philips Avent Anti Colic Baby Bottles 8 oz --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.is/products/358042968-sippy-cup-conversion-kit-for-philips-avent-natural-baby-bottles](https://www.desertcart.is/products/358042968-sippy-cup-conversion-kit-for-philips-avent-natural-baby-bottles) --- *Product available on Desertcart Iceland* *Store origin: IS* *Last updated: 2026-04-24*
