We absolutely love these bottles. The silicone is soft to the touch and easy to wash and sanitize. We alternate between these bottles and the Dr. Brown's bottles - the vents on these seen to work just as well.

Only downfall I'd say is they don't fit into the bottle holders within my diaper bag very well.

Just ordered size 2 nipples now that little man is getting bigger!

I'm 8 months into my first baby, and that has meant a lot of exploration, experimentation, and a steep learning curve. These are by far the most expensive bottles, I've bought, but they're also the best from a flow standpoint. My partner had some difficulty early on with breastfeeding, so we experimented with a lot of bottles and nipples. Of the bottles we tried, the Comotomo bottles provided the best flow for a newborn--several other bottles were like a drinking from a fire hydrant for our little angel, leading to an unpleasant experience for an infant who was able and really wanted to nurse. From my masculine, third-person observations, the Comotomo bottles and nipples also seemed to provide the easiest transition between breast and bottle--our little one could switch from one to the other during a single feeding with little-to-no coughing or sputtering. For me, I like washing the Comotomos because their wider mouths make it a LOT easier for my masculine paws to get in there, a big plus for me personally because I don't like bottle brushes. I'm just weird like that.

As our little angel grew and we got out of the house, a couple drawbacks surfaced. First, we found that none of the diaper bags we liked were designed to hold the larger diameter Comotomo bottles, so we had to choose between a bottle that didn't feed as well, but would fit in the thermal pockets of the diaper bag, or take the Comotomos and not have them stay warm. Second, when our little one started holding the bottles while feeding, he didn't like the larger diameter of the Comotomo bottles, whereas bottles with a smaller diameter that he could encompass a little more, were more to his liking. That's probably child-dependent, but there it is. Finally, my partner doesn't like the feel of the silicone bottles, which is odd for a person who uses so much silicone in the kitchen, but there you have it. Great bottles--the best--but far from perfect for us.

Hello, I would like to say I love this bottles but there's only two minor problems with them. One of them is the color that comes in only one green color for boys. I have two boys and they're both using these bottles. They are different ages. One of them is three and one of them is newborn unfortunately, with the colors being the same, we get them mixed up we have to look through the nipples to figure out which one is which if they had different colors we could've identified them better in the second minor problem is that, the measurements are very very fade so if it's late night and you're trying to feed your baby, you have to have a light on in order for you to figure out the measurements the ounces besides these ones everything is perfect

We used this while I nursed my son. In fact, we still use them now, and he is 10-months old, we've just switched the nipple to a medium flow now that he's older.

The slow flow is probably the slowest flow we found out of all the bottles we tried and we've had no problems with him switch between BFing and bottle feeding.

I love that it's just 3 pieces, SO easy to wash and dry. We dry them on a Boon GRASS drying rack and they dry within a few hours, so that we actually only need 2 bottles for 5 feedings a day. I also love that it's mostly silicone, only the rings are plastic, gives me slight peace of mind as I do sanitize the bottles by boiling quite often.

The only con I can think of is that they do leak sometimes. If the nipple is not placed perfectly, or if you shake too hard. But I find this is true with most bottles out there, so it's not a huge consideration for me.

My baby loves these bottles! Originally I got the Playtex ventaire as my niece and nephew used those and loved those. But either I got a defective box of those or they changed something with the cake that vents the air but my baby got super gassy when using the Playtex. They didn't vent well, the nipples would collapse, it was just a mess. I ordered these for her and she loved them! The two cents of the side of the nipples work amazing and she doesn't swallow a bunch of air. She's definitely a lot less gassy then before. I also love the soft silicone. It allows me to help her get the last drops of milk out of the bottle by gentle squeezing the end. The only thing I hate about these bottles is that because they are soft and squishy, they tend to be hard to open, especially if your hands are wet. It's really hard to get a good trip to open the bottles. Also they are wider then standard bottles which makes them super easy to clean, but that also means they don't fit into the standard insulated pockets in most diaper bags. That's not a big deal to me, but just something to keep in mind
