For a bottle that most closely resembles the breast, Comotomo features an ergonomically shaped nipple that is designed for a seamless transition. Constructed of a wide mound base and natural nipple, Comotomo bottles will mimic a natural feeding session without allowing the milk to dump out too quickly.

A great feature about Comotomo bottles is that they’re very easy to clean. While narrow-neck bottles are a hassle to clean and require a bottle brush, Comotomo’s wide necks can be cleaned without a brush and are dishwasher safe.

Comotomo bottles are made of silicone, which also closely mimics the feel of skin and provides comfort to your little one while feeding. Another benefit to silicone is that its 100 percent free of harmful chemicals such as BPA, PVC and phthalates.

Comotomo bottles also have dual anti-colic vents that allow air to easily flow through and keep spit-ups and gas at bay. However, the downside to Comotomo bottles is that the air vents often become blocked, which causes unwanted leakage. Therefore, you’ll always want to ensure the air vents remain unobstructed for a mess-free, enjoyable feeding session for you and baby.

If you’d like a bottle that features a trusted name and history, you’ll feel good purchasing the Lansinoh Breastfed Baby Bottles.

Lanisoh’s NaturalWave nipples are based on over 50 years of breastfeeding research and are what sets these bottles apart from others.

The NaturalWave nipple features a one-piece construction which makes it both easy for baby to latch on to and easy for you to keep clean. The NaturalWave nipple is made from flexible silicone, so it easily adapts to your baby’s individual palate and sucking motions.

The NaturalWave nipple is also clinically proven to reduce nipple confusion as it most closely mimics a natural breastfeeding session.

The bottle also features an air venting system designed to reduce baby’s intake of gas. However, the air venting system does have the potential to create bubbling, which may lead to gas in some babies.

If you find that your baby well tolerates the bottle’s air venting system, you’ll be happy to know that the bottle is BPA and BPS free and constructed of durable plastic. With its solid overall design and flexible, easy clean nipples, you can count on Lansinoh Breastfed Baby bottles to last through many happy feeding sessions with your little one.

If you’re exclusively feeding your baby breast milk you’ll want a bottle that works seamlessly along with your breast pump. The Medela Breast Milk Storage bottles are designed to fit on any Medela breast pump and allow for the milk to pump directly into the bottles.

Once filled with milk, the Medela Breast Milk Storage bottles easily attach to a nipple for a mess-free feeding session with your baby. Instead of having to pump and dump as you would normally, the Medela Breast Milk Storage System allows you simply attach a nipple onto your bottle of freshly pumped breast milk.

If you’ve pumped milk for future use or you’re taking a bottle on the go, the flat discs make storage easy, and the travel caps allow for leak-proof outings.

The drawback to the Medela Breast Milk Storage system is that the bottles are made from very thin plastic. Once boiled, the bottles begin to lose their shape and become deformed. Therefore, its recommended to use Medela Microsteam bags in order to sanitize your bottles and prevent bottles from losing their shape.

If you’d like a bottle that is not only ergonomically designed for baby but also for you, you’ll appreciate the ease of use that Tommee Tippee bottles provide. Tommee Tippee features a compact shape and three methods of positioning the bottle- cradled in the hand, a traditional hold, or held from the base.

Tommee Tippee also features a breast-like nipple to encourage easy transitions between breastfeeding and bottle feeding as well as an anti-colic valve, so air passes freely through the bottle.

Slow flow nipples are encouraged for moms who switch between breastfeeding and bottle feeding, and Tommy Tippee’s nipples are no exception. However, for some babies, the combination of the slow flow and the small nipple size means frustration and unfinished feedings. Fortunately, if you find this particular nipple doesn’t work for you, the company offers other options so you can easily swap out for one that your baby prefers.

Having a baby with reflux means the constant worry about their sensitive tummies and propensity towards gas and spit-up. The goal is always to keep as much air out of their bellies while you put food into them.

Fortunately, if your baby is primarily breastfed and also has reflux, MAM baby bottles offer the perfect solution for your little one’s special needs. The MAM Bottle for Breastfed Babies offers an advanced anti-colic system that creates a vacuum effect to eliminate bubbles which are responsible for gas.

The MAM bottles also feature a SkinSoft nipple which closely mimics breastfeeding and virtually eliminates nipple confusion. According to the company, the SkinSoft nipple boasts a 94 percent acceptance rate by babies since it so accurately resembles the natural breast.

MAM baby bottles are also surprisingly easy to clean. Unlike its competitors, MAM bottles open from the top or bottom, so it’s easy to remove stuck on milk from both ends. The only hassle associated with the MAM bottles is that disassembled, the bottle is 6 pieces, and more pieces equals more chance to lose something. Therefore, after cleaning its always best to promptly reassemble the bottle.

For the ultimate in venting advancements, look no further than the Dr. Brown’s Natural Flow Original bottle.

The unique venting system in the Dr. Brown’s Natural Flow Original bottle works through a multi-step process.

First, air enters the bottle’s collar and routes through the internal vent system. Next, the air continues through the vent tube, bypassing the milk and travels to the end of the bottle. That means your baby can continue to enjoy feeding without the possibility of unwanted air.

The bottle’s vent system is also designed to prevent aeration of the milk and vacuum pressure which prevents nipple collapse. When the milk continues to flow freely, this closely resembles a natural breastfeeding session. The nipple is also a slow flow, which allows for baby to have a steady, paced feeding. Since the slow, steady flow of the nipple is very similar to the rate and speed breastmilk is released, this helps reduce the chance of nipple confusion.

The reduction in negative air pressure helps to reduce colic, spit-up and gas while preserving Vitamins A, C and E plus lipids which are naturally found in milk.

However, along with the advanced venting system also comes the propensity for the bottles to leak, which is something to keep in mind prior to purchase. 

If your baby is having difficulty transitioning from breast to bottle, experts agree that teaching your baby to properly latch will ease that process. Appropriately named, the Latch Bottles by Munchkin are designed to effectively train your baby to correctly latch through the use of an ultra-flexible nipple.

The nipple on the Latch bottle is bendable and closely mimics the feel of a breast, which allows your baby to easily attach himself to the nipple, as well as to stay latched through the entire duration of the feeding. The Latch nipple is also stretchy enough to reach all the way back to baby’s soft palette which further ensures a proper latch.

The Latch nipple moves along with baby’s natural head movements, allowing for an uninterrupted feeding session. Latch bottles also promote infant-led feeding since the amount of milk released is based on the pressure applied and your baby’s sucking patterns.

The downside to the ultra-flexible nipples is that they are often prone to collapsing, due to their thin, bendable construction. When your baby is nearly asleep and the bottle’s nipple collapses, this can quickly startle them awake and lead to a cranky baby! This is something to keep in mind for those who rely on a bottle to soothe their baby to sleep.

Latch bottles also feature a vented air flow system for reduced gas and air bubbles, which makes them a great choice for babies with colic or reflux. However, as with other vented bottle systems, Latch bottles have a tendency to leak, which, like the collapsible nipple, is a factor to keep in mind prior to purchase.

According to Playtex, 67 percent of babies can experience the symptoms of reflux within the first four months of birth. If reflux is a concern for you and your baby, you’ll want to try the Playtex Baby VentAire bottles. These specially designed bottles utilize a patented anti-colic bottom to keep air at the back of the bottle, so no air mixes with the milk as your baby drinks.

The angled design of the Playtex Baby VentAire is ergonomically designed to support a semi upright feeding, which is the position recommended by pediatricians to help prevent ear infections.

The Playtex Baby VentAire features a wide, Naturalatch silicone nipple designed to closely resemble the look and feel of a breast, which makes for a seamless transition between breastfeeding and bottle feeding.

Playtex Baby VentAire bottles are also easy to clean and feature a removable top and bottom. And while Playtex Baby VentAire bottles feature less parts than competing models, they still have several removable pieces that you’ll be responsible for cleaning and keeping up with. Therefore, if simplicity from a bottle is important to you, you may want to skip the Playtex Baby VentAire bottles. However, if you’d like to easily switch between breast and bottle feeding while reducing the amount of air bubbles your little one consumes, don’t hesitate to give the Playtex Baby VentAire bottle a go!

If your baby is prone to colic and gas, it’s important to find a bottle that allows enough air to circulate through. This results in fewer air pockets, which are to blame for spit-ups, gas and irritability. Philips Avent Natural Baby Bottles offer advanced air flex vent technology which lets air flow freely through the bottle and away from your baby’s sensitive tummy.

Philips Avent Natural Baby Bottles are also a great choice for breastfed babies, as they feature a soft, flexible silicone nipple with a wide design that mimics the feel and latch of the natural breast. The design of the nipple is crucial in preventing nipple confusion, as the closer the nipple resembles the breast, the less likely your baby will be to reject breastfeeding in favor of the bottle.

The nipple on the Philips Avent also features a comfortable spiral design paired with a slow flow rate, so baby will remain content throughout their feeding. The wide neck bottle is smartly designed to allow for ease of cleaning and filling.

Due to the design of the silicone nipple, the spot where it connects to the ring is a bit prone to leakage. Always take care that the bottle is tightly closed before each use, to allow for an uninterrupted feeding session with your baby.

Here’s an interesting fact for breastfeeding moms. Milk naturally flows from several holes in your nipple, instead of through one single duct. With the multi-flow of milk that your breasts provide, NUK Simply Natural was designed to closely mimic that flow, and features multiple nipple holes in their bottles.

In this 9-piece gift set, you will get two 5 ounce bottles and two 9 ounce bottles, both with medium flow, multi-hole nipples. You’ll also get two additional nipples that feature a fast flow, for when baby gets older or needs a quicker feeding. Like the medium flow nipples, the fast flows also feature multiple holes for a realistic simulation of the breastfeeding experience.

Also included in the set is three orthodontic pacifiers, to help calm and soothe your baby between feedings.

The downside to NUK Simply Natural bottles is that they are constructed of a brittle plastic and are prone to cracking if dropped. Microwaving these bottles may further their propensity to crack, and for this reason, the company advises that they’re not microwave safe. However, according to the company, the NUK Simply Natural bottles are dishwasher safe, as long as they’re used on the top rack. Still it’s best to always take extra precaution with these bottles since they’re prone to breakage.
