Anti-colic bottles have some mechanism for reducing the amount of air baby can swallow during a meal. Swallowing air can create uncomfortable pressure and gas in a baby's tummy, and is considered a common cause of post-bottle fussiness. Not all babies are sensitive to swallowing extra air, so not all parents need to investigate anti-colic bottles.
Some anti-colic bottles have a vent system that forces air out of the bottle so it doesn't enter baby's mouth. One of the most popular... anti-colic bottles, Dr. Brown's Natural Flow, has a long straw that extends from the base of the nipple to the bottom of the bottle, so the air travels to the opposite end from where baby is drinking. Other bottles, such as Similac SimplySmart and Evenflo Bebek, have a vent built in to the nipple. The vent allows air to escape at a different part of the nipple, so it doesn't travel out with the milk as baby drinks.
Another popular anti-colic bottle style uses disposable bags to hold formula or milk. As baby drinks, the bag collapses an no additional air is allowed into the bottle. Other bottles are shaped in such a way that air is directed up and away from the nipple.
The following bottle styles are made to reduce the amount of air getting to baby through the bottle, with the goal of reducing fussiness and pain after their meal.

Dr. Brown's Natural Flow bottles come in several styles. You can choose from wide neck or standard neck bottles, as well as from plastic or glass. All of the Natural Flow bottles have a special internal vent system that reduces the potential for discomfort for your baby. The bottles also prevent fluid in the ear, which can also cause fussing and discomfort.
The internal vent system looks like a long straw within the bottle. A ring sits in the top of the bottle and the long, straw-like vent... extends the whole length of the bottle.
The standard neck bottles are available in 2 ounce, 4 ounce and 8 ounce sizes. The wide neck bottles are available in 4 ounce and 8 ounce sizes. All of the Dr. Brown's Natural Flow bottles have a clear silicone nipple. You can purchase various flow speeds in the nipples, too, as well as multi-packs with different sizes of bottles and nipples.

The discomfort caused by ingesting air during feeding is thought to be a cause of colic, so these Tommee Tippee Closer to Nature bottles are specially designed to help reduce air bubbles in the milk. They also encourage a good latch-on during feeding thanks to a wide base on the silicone nipple. The more natural feeding position also helps baby take in less air. These bottles have a tube that extends from the base of the nipple down to the bottom of the bottle so that the air flows out away... from baby's milk.
These bottles are available in 5 ounce and 9 ounce sizes. They come in 3-packs, doubles, and singles.

With only 4 parts, a wide bottle neck, and rounded corners, these bottles are among the easiest to clean of any anti-colic versions. Avent bottles are clinically proven to reduce colic and discomfort. The Airflex venting system reduces air ingestion. As your baby eats, the integrated valve in the nipple flexes to allow air into the bottle to prevent vacuum build up and vents the air to the back of the bottle. It keeps the air in the bottle away from the baby’s tummy to help reduce gas, spitting... up and other discomfort. Newer versions are updated to be easier to use without leaks. Avent bottles are available in 4 ounce and 9 ounce versions.

Ventilation holes in the base of the MAM Anti-Colic bottles are what keep air bubbles and gas out of baby's mouth and tummy. The nipples are silicone, but they have a soft skin-type texture to feel more natural for baby, and they're designed so they don't slip out of baby's mouth easily. That means fewer interruptions where baby unlatches from the bottle, which also reduces air intake. The removable base and cap can be used to sterilize the bottle in the microwave in less than 3... minutes. The top ring and nipple go inside the base with some water, and the lid goes over the top to create a sterilizing steam bath. The cap also doubles as a measuring cup for formula, and it is very good at preventing leaks if you're out and about. MAM Anti-Colic bottles are available in 5 ounce and 9 ounce sizes, and the nipples come in newborn, level one, and level two flow options. Multi-packs and starter sets are available, too. These bottles are available in soft neutral colors, as well as pink, purple, and blue.Continue to 5 of 5 below.

Similac Simply Smart bottles have a vent in the nipple to help reduce fussiness from swallowing air. There's a silicone mixer piece inside the bottle that acts as a mixer to break up clumps of formula. The SmartClose ring has little windows on each side to show you when the bottle is closed properly. That helps avoid leaks.
These bottles are available in 4-ounce and 8-ounce sizes. The bottles can be purchased as single packs, 2-packs, and in starter sets with four or more bottles. The nipples... are available in 2-packs that are slow flow, medium flow, fast flow or y-cut for thicker formulas. You can also purchase a formula container cap so you can pre-measure powder formula and carry it with you easily.
These bottles are increasingly difficult to find in stores.
