The Comotomo is a unique bottle like nothing else in this review. It is made entirely of silicone and ranked third winning a Top Pick award for innovation. This bottle has a squeezable shape and breast like nipple and bottle shape. The opening is super wide for easy cleaning and milk transfer. The bottle is easy for mom and dad to use and for baby as well. This bottle is one with few downfalls and is one we would recommend to a friend who is looking for something a little different.
Pros: Silicone, let down action, latch nipple
Cons: Unstable when standing, longer to warm

There is a lot to like in this interesting bottle that has a design and features like no other. This bottle did not leak during transport, but the cap does pop off easily. Transport is when leaking can be the most annoying because it gets messy and baby doesn't get a chance to feed on the full amount. This bottle does have some leaking while baby feeds around the nipple, but this is sort of a natural result of breastfeeding and happens with mom as well. Some parents might find this annoying, but we can easily forgive it as a sign that the nipple closely matches that of mom.
We really like the nipple on this bottle and consider it to be one of the best in the bunch. The nipple and mound itself are the closest thing to a real breast that we found in this review. The soft silicone has a very natural feel and allows for an easier transition from breast to bottle than the rest of the competition. The dual anti-colic vent valves don't interfere with feeding and the silicone bottle can be manipulated by baby or parent to squeeze milk out for a similar effect to milk let down in mom. Our baby testers really seemed to enjoy this nipple.
The Comotomo is also very easy to clean and is clearly thoughtfully designed to be so. The super wide mouth neck can be hand washed without a bottle brush and the limited number of piece mean it will be a quick process without a lot of trouble or effort we found in some of the competition that had a lot of pieces or hard to reach nooks and crannies. There are some plastic parts, which can retain smells and be difficult to clean, but overall cleaning this bottle is relatively painless.
This bottle is easy for babies to use, even if parents might struggle a little (see our dislikes below). The bottle itself is ergonomically shaped and the squishy silicone material is easy for baby to clasp and massage as desired. We like that it isn't made of plastic but there is still no risk of it breaking, even if it is dropped or thrown by older babies; it almost bounces when it falls! It also has no complicated venting system inside the bottle that requires assembly or cleaning and the dual vents on the nipple work well and still allow for beneficial circulation of air.
We do like the silicone materials for the bottle body over the plastic options in this review, but we still think glass is a better choice with fewer chances for health related problems.
Our dislikes of the Comotomo are few, but should nevertheless be considered when making a bottle purchase. The wider nipple design and latching will cause some leaking while baby is feeding. Depending on your baby it can be significant, it is usually on par with breastfeeding, but we imagine some parents would consider it a deal breaker if their goal is 100% no leaking.
While this bottle is easy for baby to use, which is arguably the most important part, it isn't the easiest for parents to use. The same ergonomic shape we like for baby means the bottle has a tendency to tip over while filling it and we found you almost have to hold the body while filling to avoid spilling. The base of the bottle is also unsteady thanks to shape and the softness of the silicone. This makes screwing the collar on over the nipple more difficult than most of the firm body bottles made of plastic or glass, thought the Philips AVENT Natural Glass bottle is hard to thread than this one.
Other ease of use dislikes are minor, but include slower warming times due to the silicone material of the body, it can only be used with special bottle warmers designed for wide-mouth bottles, it is heavier than the plastic bottles (though still lighter than glass), and the markings are hard to read. The volume markings on this bottle while difficult to read, are etched into the silicone so cannot be washed or rubbed away over time like many of the plastic bottles we looked at.
While we prefer the silicone body over plastic for eco-health, we still like glass better for many reasons you can read about in our article on plastic in bottles and sippy cups. This bottle is made in Korea and we prefer those made in the USA or Europe.
The Comotomo is a special little bottle that is easy for baby to hold, use, and latch onto. The unique silicone body and nipple help create a breast like feeding experience that seems to help baby transitions easily back and forth from bottle to breast without trouble. This bottle has zero risk of breaking and is a good value compared to glass options in this review. It is an innovative bottle that is tough to compare to the rest of the group given its lack of similarities in design or materials. Overall we think it is a nice user friendly bottle in a stylish package with only minor downsides that affect parents more than baby.
