How To Put Together A Dr. Brown Bottle In 3 Easy Steps

Did you know Dr. Brown bottles help to reduce colic, gas, and spit-ups in babies? It’s true. Our twin girls drank from these bottles during their time in the NICU (Neonatal Intensive Care Unit) and then, at home when they were discharged. As I write this, they are both currently drinking from these bottles like a champ. So yes, I do love these bottles for a few reasons and I will share the benefits in just a sec but first things first…here is how to put together a Dr. Brown bottle in 3 simple steps.

Step 1. Snap the bottle nipple into the white seal.

To be sure the bottle nipple is secure, make sure you hear a suction sound or light snap.


Step 2. Put together the vent kit.

Place the small green vent into the vent holder.

This is what makes Dr. Brown’s bottles so uniquely great…the venting kit. This special feature is what removes a good portion of the air bubbles from the bottle when your baby drinks from it.


Step 3. Now, put all pieces together!

Place the vent kit into the bottle and seal it with the bottle nipple top.

What Are Dr. Brown Bottles?

Dr. Brown bottles can be a convenient solution to feeding your baby especially if they are gassy, colicky, or have frequent spit-ups.

These bottles are designed to create a natural flow and reduce air bubbles in baby’s milk.

These bottles are made from BPA-free materials and come with a patented two-piece vent system to ensure your little one isn’t ingesting any nasty chemicals.

Dr. Brown’s bottles also come with a unique nipple design that allows babies to feed steadily while providing additional support for their teeth and jaw development.

One of the main benefits of using a Dr. Brown bottle is the internal vent system which helps to minimize colic, spit-up, and gas while allowing your baby to drink at their own pace.

As compared to standard bottles, these bottles are especially beneficial for reducing air intake during feeds to help reduce symptoms like fussiness and discomfort.

With their focus on health and safety, it’s no wonder Dr. Brown bottles were the preferred choice in the NICU while our twin girls were there.


What is the green insert in Dr. Brown’s bottles?

As previously mentioned, this is the “venting system” or what helps to reduce colic, gas, and spit-ups during bottle feeding time. This insert also helps to preserve nutrients in breast milk and formula, to provide your baby with a similar feeding experience to breastfeeding.

When can you remove the internal vent system?

As soon as your baby gets a little bigger and can sit up on their own, eat some solid foods, or not be as gassy, colicky, or have reflux.

Why are my bottles leaking during feeds?

This usually comes down to the nipple flow, which may be too slow for your baby. When this happens your baby will suck harder and harder to get more milk out which pushes air into the vent. If too much pressure builds up in the vent then it may leak pushing milk out of the white seal (aka collar). To prevent this, try switching to the next nipple flow level.

For instance, my girls started off with the “preemie” nipple flow. One of my daughters was sucking so hard that milk came out of the collar. This was a sign for me to increase their nipple flow to the next level up which was the “transition” nipple.

How do you prevent the bottles from leaking during traveling?

The first time I took Dr. Brown’s bottles to my twin’s first ped appointment was a mess. I did not secure the bottles upright (thinking for some reason they wouldn’t leak or spill). Luckily I had a couple backup bottles AND had them in a zip-lock baggie so the milk spill didn’t get everywhere.

To ensure your bottles do not leak, keep them upright in a secure spot whether that be in your diaper bag, purse, etc. OR to be on the safe side, you can get some inexpensive Dr. Brown travel storage caps. Just pop one of these spill-proof caps on your bottle and away you go! Don’t forget to pack the bottle nipple and white seal for your babe to feed when needed.


To Wrap It Up

There you have it! 3 super easy steps to put together your baby’s Dr. Brown bottle.

If you are looking for a quality bottle to help reduce colic, gas, and spit-ups in your little one then I highly recommend giving these bottles a try as they’ve worked so well for our girls.
