Dr. Brown’s® Sippy Straw Bottle Conversion Kit – Narrow

It was a lifesaver to find a conversion kit that fits my baby’s existing bottles, the straw is just the right length for them to master. The soft spout made the switch from nipple to straw so much easier than I expected, and it hasn’t leaked once.

My little one took to this straw kit right away—the soft silicone straw is gentle on their gums, and it fits perfectly on the bottles we already have. No more wrestling with a separate cup at mealtime.

The soft silicone straw is perfect for my 8-month-old's new teeth, and it fits right onto our existing bottles without any leaks. She actually picked it up and started sipping on the first try, which I did not expect.

My little one had been struggling with regular sippy cups, but this conversion kit let her use her familiar bottle while learning the straw—the one-piece valve is super easy to clean and hasn't leaked once.

The valve is leak-proof enough that I can toss this in the diaper bag without finding puddles later, and the straw flow rate feels just right for a beginner. My baby took to it on the second try, so the transition from nipple to straw was smoother than I expected.

Our 10-month-old picked up straw drinking in just two tries with this conversion kit, and the valves keep spills at bay. I love that we can use the same bottles we already have. The straw is firm enough for her to chew on but still works perfectly.

This kit saved us from buying whole new cups — the straw valve is sturdy enough that my 10-month-old can actually get the liquid without choking. Cleaning is a breeze since it comes apart easily, and the fact it fits the narrow bottles we already have is perfect.

My baby’s been struggling with regular sippy cups, but this conversion kit clicks right onto the bottles we already have, so there’s zero learning curve for me. The straw is soft and flexible enough that she didn’t even fuss—just started drinking immediately.

The valve mechanism is just tight enough that my 18-month-old doesn't flood herself, yet she gets a good flow with a little effort. I love that it fits the bottles she's already used to, making the switch from nipple to straw seamless.

My 10-month-old figured out the straw part within a few tries, and I love that it fits right onto the bottles we already had. The silicone straw is soft enough for her gums but sturdy enough not to collapse.
