## Questions & Answers

**Q: Will this kit fit the Philips Avent Anti-colic or Classic bottles?**
A: No, it does NOT. This conversion kit is exclusively designed for Philips Avent Natural bottles (the ones with the wide neck and curvy shape). It is compatible with both Plastic and Glass Natural bottles (4oz, 9oz, and 11oz).

**Q: Can my baby drink from the bottle while lying down or reclining?**
A: Yes, absolutely! The straw features a weighted gravity ball at the end that moves with the liquid. This allows your baby to drink comfortably in any position—whether sitting upright, reclining, or even lying down—without swallowing air.

**Q: Does the nipple leak if the cup is turned upside down or shaken?**
A: It is spill-proof. Our silicone spout nipple is designed with a variable flow valve that only releases liquid when your baby sucks on it. If held upside down or dropped, it won't create a mess. Please make sure all parts are assembled tightly.

**Q: How do I clean the straw? Is it hard to get the milk residue out?**
A: Cleaning is very easy. We recommend disassembling the parts and using the brush to clean inside the straw with cleaning brush after every use. All parts (nipples, straws, handles) are also top-rack dishwasher safe and sterilizer safe.

**Q: I have the Avent Glass Natural bottles. Are the handles and screw rings heavy enough to hold the glass bottle securely?**
A: Yes! These handles are sturdy and ergonomically designed to fit Philips Avent Natural Glass Bottles perfectly. They provide a non-slip grip that makes it much easier for your little one to hold the heavier glass bottles independently.
