I love these bottles since it's the only thing my baby would take (we tried MANY bottles before the Comotomo ones). I ruined one of the nipples because my nipple brush has the twisted wire end and I didn't realize it had come undone... VERY sharp point on the end of that metal! It poked a hole through one of my nipples, but it's totally not any flaw of the nipple - it was my mistake for not realizing the nipple brush became sharp. I was glad to see I can get replacement nipples and that they have a variety of flow levels. That way I can increase the flow without having to necessarily buy the bigger bottles! YAY! They don't have markings on the nipple indicating the speed (at least mine don't), but it's not that hard to figure out. 1 hole is slow flow (0-3 months) 2 holes is medium (3-6 months) 3 holes is fast (6 months) Y cut is variable I don't pay attention to the ages though - my 5 month old still uses the slow flow nipples at this time (0-3 months). I don't want her to get used to the bottles being "easier" and then no longer take the breast. She only eats from bottles 3 times per day, 5 days a week and the rest of the time she's breastfed. I may get faster nipples later on as she gets older so it won't take as long for her to eat. It definitely won't be until after she starts solids though. ***************************HERE'S MY FULL REVIEW OF THE COMOTOMO BOTTLES(since Amazon won't let me link it!):******************************************** We tried to introduce bottles around 10 weeks but it didn't work, even when I left the house for 20-60 minutes. Since I wasn't going back to work until 14 weeks, we didn't try too hard since it didn't seem worth it to upset her so much when she didn't NEED to take a bottle yet. Luckily, my husband took 6 weeks off work after I returned to work before we started her in daycare, so he would be the one trying to introduce her to bottles instead of a stranger. I prepared for my first day back to work by purchasing many, many different types of bottles for my husband to try. On that first day, our daughter did not eat for 10 hours. My husband tried many different bottles (but not all) by the time I got home. A nurse at her doctor's office said to NOT offer her the breast when I got home, because she would learn that if she held out long enough she would get mommy's breast. So when I got home I tried two more bottles, the Comotomo one being the second. She sucked down 3 ounces! And I was the one feeding her! Two hours later, she took another three ounces. When my husband tried to offer her the Comotomo bottle the next day she refused it at first, took a 30 minute nap, and then she accepted it and drank 3 ounces. We tried SEVEN different bottle/nipple combinations before this one: Dr. Browns, Avent, Playtex (3 different nipple types), Medela, NUK. We were going to try some others but I noticed their nipples weren't TOO different than what we already tried... and the Breastflow bottles I didn't think would make a difference either. I felt like it was the nipple base size that didn't work for her with other bottles, and I was right. I have very large breasts, and the Comotomo nipple pressed against her nose and cheeks like she is used to while feeding. I swear that is what made the difference. I immediately ordered two more. I don't care about the price - if you feel it's too expensive, either you have a baby that WILL take another bottle (and then you don't HAVE to use this one), or this is the only thing that works and you are actually so cheap that you put a price on getting your baby to eat. Maybe after she gets used to bottle feeding, a normal less-expensive bottle will work. I do like a lot of things about this bottle: - It works! - The nipple base is very large so it presses against my baby's nose and cheeks like a real breast. - It allows baby to latch on the same as with a breast. - It doesn't leak. You have to squeeze it to get some out... it won't even drip if you don't! - It's squeezable. - It's only 3 parts. - It fits in my Munchkin bottle warmer (the 2006 model... a hand-me-down that works great!) - It's durable - I've had hard plastic and glass break on me when dropping a bottle. This doesn't break. - Easy to wash. - Even at 3 months, the baby can kind of hold on to it. I think it will be easy to use for self-feeders. - My daughter can get every last drop out of the bottle - no breastmilk wasted! - It's cool looking. - It has air vents. - The lids are secure and hold the nipple in place so even if you squeeze the bottle, nothing comes out in the lid. I don't like: - It's hard to read the ounces... but on the other hand, the markings can't wash off! - I can't pump directly into it - but honestly they are so expensive and I produce so much that there's no way I could use these as storage containers. I use Mother's Milkmate. I don't know if our Inchbug labels stick to it yet. Those are supposed to stay on even through the dishwasher, but I'm wondering if that will work on this material. I will update when I find out. I might just buy an Orbit label instead (also from Inchbug) if it doesn't work. UPDATE: I've used the Inchbug small rectangle labels and affixed them to the collar of the bottle and they have not worn off. The two teachers in my daughter's daycare room really like the bottles because they aren't breakable, don't leak, and look neat. We still love these bottles and I have yet to try regular ones again since these are working so well. I still only have 3 bottles, which is exactly how many she needs for a 6 hour day.
