Dr. Brown's Natural Flow Narrow Baby Bottle Silicone Nipple, 2-Pack - Level 4 (9m+ Fast Flow)

My baby recently moved up to Level 4 nipples and these have made feeding so much easier. The flow is steady without being overwhelming, and my little one seems much more satisfied after each bottle. The silicone feels soft and durable, and cleaning is quick. Having two nipples in the pack is very convenient.

After trying several nipple sizes, Level 4 turned out to be exactly what my baby needed. Feedings are faster and more comfortable now. The natural flow design helps reduce fussiness, and I appreciate the quality of the silicone material.

These nipples are made from sturdy silicone that holds up well after repeated washing and sterilizing. My baby accepted them immediately, and I noticed fewer interruptions during feeding sessions. Definitely a worthwhile purchase.

I was worried about moving to a faster flow nipple, but the transition was smooth. My baby adapted right away and seems much happier during bottle time. The design works exactly as described and feels very reliable.

These are perfect replacements for our existing bottle setup. The fit is secure, and there have been no leaks. The flow rate is consistent and helps my baby finish bottles comfortably without frustration.
