Review: Made Transition from Bottle to Sippy SO Easy! - So helpful to transition from bottles to sippy cups. It took her a bit to understand the straw part. Eventually we just stopped using them and she could drink it like a cup. Worked perfectly with our glass bottles. No leaks, high quality, great for little hands! Review: Game changer! - I cannot tell you how much we love these! They fit perfectly with the advent bottles. It helped us transition from the bottle nipple to a suppose cup. Sometimes we have to take it back off and put it back on to get milk flowing (feels like something with pressure) or shake it, but our son has figured it out. No issues with leaking and relatively easy to clean. ## 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 issues with leaking and relatively easy to clean. ### ⭐⭐⭐⭐⭐ Get More Use Out of Your Bottles *by E***Y on August 17, 2025* 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! ## 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.us/products/358042968-sippy-cup-conversion-kit-for-philips-avent-natural-baby-bottles](https://www.desertcart.us/products/358042968-sippy-cup-conversion-kit-for-philips-avent-natural-baby-bottles) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-06-01*
