How To Fix Leaking Dr. Brown Bottles

The Problem with Leaking Bottles

Dr. Brown bottles are a popular choice for parents who want to reduce colic in their babies. However, one of the biggest complaints about these bottles is that they often leak. This can be frustrating for parents who have to deal with the mess and waste of milk or formula. But why do these bottles leak in the first place?

The Cause of Leaking Bottles

The most common cause of leaking Dr. Brown bottles is a problem with the venting system. This system is designed to prevent air from entering the bottle while the baby is feeding, which can cause colic. However, if the venting system is not working properly, air can enter the bottle and cause leaks.

How to Check the Venting System

To check the venting system, first, make sure the bottle is clean and dry. Then, remove the venting system from the bottle and inspect it for any cracks or damage. If the venting system is damaged, it will need to be replaced. If it looks fine, reassemble the bottle and test it by filling it with water and turning it upside down. If water leaks out, the venting system may need to be adjusted.

How to Fix Leaking Bottles

If you’re dealing with a leaking Dr. Brown bottle, there are a few things you can try to fix the problem.

Tighten the Bottle

One of the most common reasons for leaking bottles is that they are not tightened enough. Make sure to screw the bottle together tightly to create a secure seal. However, be careful not to overtighten the bottle, as this can cause the bottle to deform and leak.

Adjust the Venting System

If the venting system is not working properly, adjusting it can help fix the problem. Try loosening or tightening the venting system to see if this makes a difference. You may also want to try removing the venting system entirely to see if this solves the problem.

Replace the Venting System

If the venting system is damaged, it will need to be replaced. Dr. Brown’s sells replacement venting systems that are easy to install. Simply remove the old venting system and replace it with the new one.

Use the Right Nipple

Using the right nipple can also help prevent leaking. Make sure to use the nipple that is designed for the bottle size you are using. If you are using the wrong nipple, it can cause leaks.


Leaking Dr. Brown bottles can be frustrating, but there are several things you can do to fix the problem. Make sure to check the venting system, tighten the bottle, adjust the venting system, replace the venting system if necessary, and use the right nipple. With a little bit of effort, you can enjoy leak-free feeding with your Dr. Brown bottles.
