They are easy to clean, rarely leak, and are just the right flow. Would definitely recommend. ### ⭐⭐⭐⭐⭐ Love this! *by J***T on March 18, 2026* Greta product! Very useful and durable. ### ⭐⭐⭐⭐⭐ Excellent Quality, Perfect Flow for Growing Babies *by S***E on January 19, 2026* We have been using Dr. Brown’s bottles from the beginning, and the Size 4 nipple has worked really well as our baby grew. The flow is perfect for an older baby who feeds faster, and it helps reduce fussiness during feeding. The quality is excellent, just like all Dr. Brown’s products, and it fits perfectly with the bottles. Easy to clean and durable too. Definitely a good product and worth buying if your baby is ready for the next flow level. ## Frequently Bought Together - Dr. Brown's Original Nipple, Level 4 (9m+), 6 Count - Dr. Brown's Natural Flow Anti-Colic Options+ Narrow Baby Bottle, 8 oz/250 mL, with Level 1 Slow Flow Nipples, 0m+, 4 Pack --- ## 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.hr/products/23993008-natural-flow-level-4-baby-bottle-silicone-nipple-fast-flow](https://www.desertcart.hr/products/23993008-natural-flow-level-4-baby-bottle-silicone-nipple-fast-flow) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-06-19*
