Why Dr Browns Narrow Level Medium Flow Is Necessary
I started looking for medium-flow nipples because my baby was getting frustrated with the slow flow and taking too long to finish a bottle. I wanted a flow that matched her age and appetite.
I cared about the anti-colic vent, since gas and fussiness after feeds were a real problem for us. I was looking for a bottle system that could actually help with colic, not just promise it.
I also wanted bottles that are easy to clean and a set that grows with my baby. Buying new nipples every month is wasteful, so a set with multiple levels made sense.
My Buying Guides on Dr Browns Narrow Level Medium Flow
Why I Looked for Dr Browns Narrow Level Medium Flow
I looked for medium-flow nipples because my three-month-old was frustrated with slow flow. A nipple that matches the baby's age makes feeding calmer for everyone.
What I Check Before Buying
I check the flow level against my baby's age first, since too fast can cause choking. I also look at the anti-colic vent and whether the nipple is 100 percent silicone.
My Preference for Narrow or Wide-Neck Bottles
I prefer narrow bottles for the classic Dr. Brown's feel, but wide-neck bottles are easier to fill and clean. Narrow suits travel, while wide-neck suits home use.
What I Look for in Quality
I look for soft, durable silicone nipples and bottles that do not hold odors. Glass is great for cleanliness, while plastic is lighter for outings.
How I Compare Prices
I compare the cost of a nipple six-pack against a full starter set, since a set often costs little more and includes bottles and extras. A six-pack is best if you already own bottles.
My Tips for Choosing the Right One
My main tip is to watch your baby, not just the age label. If feeds take forever or your baby falls asleep hungry, it may be time to move up a flow level.
Final Thoughts
After testing these Dr. Brown's options, the Level 2 six-pack of nipples is my top pick if you already own bottles, while the narrow glass starter set is the best complete buy for a new parent. Both made feeding calmer in our house.
If your baby is three months or older and frustrated at feeding time, try the medium flow. Watch how they handle it, and move up only when they are ready.
