Why I Love Dr. Brown Bottles
I didn’t really know much about Dr. Brown bottles other than my sister used them with her kids and I was told they had the best nipples.
I happened to get a couple in the mail for free so I went ahead and tried those after I stopped breastfeeding.
I loved them!

They have an innovative venting system designed to help preserve vitamins, prevent air bubbles, offers a flow rate that supports breastfeeding, and reduces symptoms of colic like spit-up, burping, and gas.
I’m not sure there’s another bottle out there that does all of that. But why do Dr Brown bottles leak?
A couple of months in I noticed they would leak from time to time even though I prepared the bottle the same way every time.
It seemed strange that it would only happen sometimes and in different amounts.
I loved my Dr. Brown bottles though, so before I threw them out I did some research to figure out if I was doing something wrong.
Sure enough, I wasn’t the only momma experiencing this. Good news…you can prevent them from leaking when used correctly!
Why Do Dr. Brown Bottles Leak?
The culprit of the Dr. Brown bottles leaking is improper handling of the venting system. Milk or formula can get into the vent and exit the bottle when the bottle isn’t prepared or fed to your baby properly.
How to Fix Them
Don’t Overfill the Bottle
Make sure you don’t fill the bottle past the maximum amount (either 4 or 8 ounces depending on which size you have). Be sure to include how much room the formula powder will take up as well. If you fill the bottle to the maximum level of 8 ounces then adding the formula after will overfill it. I always either add the formula before I fill it with water or leave an ounce of room for the formula when I fill it with water.
Don’t Shake the Bottle with Vent in Place
Make sure you shake the bottle without the venting system in place. This prevents the formula from getting into the vent and leaking out. You can either use a Dr. Browns storage cap to shake it or you can stir the formula instead of shaking it, which also reduces air bubbles.
Don’t Heat the Bottle with Vent in Place
Don’t heat the bottle with the venting system in place. When the formula or milk heats up it expands, forcing the milk into the vent and allowing it to leak when you feed your baby. Always let the bottle cool down before you put the venting system in to prevent your Dr. Brown bottles from leaking.
Don’t Over or Under Tighten the Lid
When you over tighten the lid it can cause too much pressure to build up, which forces the milk or formula into the vent and then leaks out. When you under tighten the lid it doesn’t allow the bottle to form the seal it needs to prevent the milk or formula from leaking out.
Don’t Submerge the Vent Tube in the Milk/Formula While Feeding
While you’re feeding your baby, don’t submerge the vent tube into the milk or formula since it will leak out. I recommend holding the bottle at a 45-degree angle. If you do get milk or formula in the vent tube, just hold it upright and loosen the nipple to release the built-up pressure. Then re-tighten it to form the seal.
Use the Appropriate Size Nipple
If the nipple size (size of the hole) is too big, your baby might blow back into the bottle, which can cause the liquid to get into the vent and leak out. If the nipple is too small, your baby might suck extra hard, which can cause the nipple seal to break and the milk or formula to leak out.
