Comotomo vs Philips Avent Natural is the bottle decision for breastfeeding parents who need their baby to take a bottle without giving up the breast. Both have wide, breast-shaped nipples and both are sold as the bottle for combination feeding. They get there with different materials and different ideas about flow. Here is how they compare and which to try first.
Quick Verdict
Try the Philips Avent Natural first if your main worry is flow. Its Natural Response nipple releases milk only when the baby actively sucks, which is the closest match to how breastfeeding works and helps prevent a preference for the easier bottle. Try the Comotomo first if your baby refuses firm bottles, because its soft, squeezable silicone body and wide mound feel more like skin. Comotomo is also the easiest bottle on the market to clean. Buy one of each before you buy a set: the baby chooses.

Nipple and Latch
Both nipples are wide so the baby opens the mouth as at the breast. Comotomo's is softer and sits on a broad silicone mound that babies can press their lips into. Avent's is a little firmer with a defined shape. Babies who reject one often accept the other, and there is no way to predict which.
Flow
This is the biggest practical difference. Avent's Natural Response nipple has a tip that opens only under suction, so milk stops when the baby pauses, the same as at the breast. Parents need to pick the right flow number, and some babies get frustrated until they do. Comotomo flows more freely. That makes it easy for babies to accept, but for a baby who also nurses, paced feeding matters more to avoid a preference for the faster bottle.
Gas and Colic
Both vent through the nipple with no extra straws or inserts. Neither is as thorough at reducing air as a full internal vent system, but both do well for most babies. Check that Comotomo's two small vents are open and facing up, since a blocked vent collapses the nipple.
Materials and Cleaning
Comotomo's silicone body is soft, light, and safe in boiling water, the dishwasher, and a sterilizer. The neck is wide enough to clean by hand without a brush. Silicone can cloud a little and hold odor over time. Avent comes in plastic or borosilicate glass, both with wide necks and easy cleaning. Glass suits parents avoiding plastic altogether.
Price and System
Avent is far cheaper per bottle, comes in more sizes, and its bottles fit Avent pumps and many storage systems. Comotomo costs about twice as much per bottle and has only two sizes, and its soft base can tip when full.
Who Should Buy Comotomo
Babies who refuse firmer bottles, parents who want the easiest cleaning, and families who like soft silicone over plastic.

Frequently Asked Questions
Which is better for avoiding nipple confusion?
Avent Natural has the edge because milk flows only when the baby sucks. With any bottle, use the slowest flow and pace the feed.
Do Comotomo bottles leak?
Rarely if the ring is seated evenly. Most leaks come from a collar screwed on crooked or too tight.
When should I change nipple flow?
When feeds take much longer than 20 to 30 minutes or the baby collapses the nipple. Breastfed babies often stay on a slow flow for months.
