Pros: Healthy materials, breastlike nipple, lightweight
Cons: Falls over easily, slow warm time
Our Analysis and Test Results
Just a few years ago, Comotomo was pioneering the field of silicone bottles, and it was unlike any other bottle we encountered before. Now there are a few more silicone options on the market, but the Comotomo is still one of the best.
There is a lot to like about this baby bottle. It is one of the easiest to use in the bunch, with only three parts to assemble for feeding the Comotomo keeps it simple. There is even a small tab on the side of the nipple ring to help you screw it on tightly.
While we never experienced any leaks from this bottle, the nipple cap snaps on to catch any stray milk. Cleaning the Comotomo does not require a bottle brush thanks to its super wide mouth opening. You will still want a smaller brush to clean the nipple, but overall the process is relatively quick and painless. We appreciate the size of the opening when transferring breastmilk or mixing formula, as the wide neck makes it easier to avoid spills and messes.
Having a silicone bottle gives you the best of both worlds.you the lightweight feel of plastic with the peace of mind from using a healthy material similar to glass. Also, the body of this bottle is soft and pliable, making it easier for baby to grab with tiny hands. It has a large nipple mound that closely resembles mom's breast, making it easier for baby to get a good latch and perhaps better for little ones who are primarily breastfed.
Every bottle will have a few flaws, and the Comotomo is no exception. The soft silicone body and relatively small base make it more likely to tip over. We had no problems with leakage when the bottle was held upside down, but the squishable nature of the body can cause accidental leakage if squeezed. You will have to take extra care if you want to toss it in the diaper bag, but the nipple cap also helps with this. Be warned it pops off more easily than we would like, and may not catch every spill.
The volume markings are merely a different texture of silicone on the side of the bottle, and they are somewhat difficult to read in low light. Silicone is a natural insulator, which means you will have to wait a bit longer for warm milk than you would with plastic or glass. The nipple is softer than average, and some parents find that in combination with the pliable silicone body, a vacuum is sometimes formed that causes nipple collapse despite the vents.
Last, we love that most of this bottle is made from silicone. However, the rim is made from PPSU plastic, and the milk will come into contact with this when feeding. It is better than using only plastic, but other silicone bottles manage to eliminate any plastic on the inside of the bottle, sealing silicone with silicone to create a plastic-free environment.
Overall, the Comotomo is a bottle we adore, and babies love to use. Its silicone material will bring peace of mind to the health-conscious, with the durability you won't find in glass, and the simplicity of cleaning and assembling will keep your feeding times running smoothly. The Comotomo is a bottle that will keep any mom happy.
