5oz/9oz Kid Kanteen® Baby Bottles

We have gone through so many bottles, the Avent system and Born Free glass bottles. My concern was the possible other chemicals in the plastic bottles so we switched to the Born Free glass bottles. Those bottles are great, the venting system, the size of the bottle etc. however we have broken almost all of the bottles which make it an expensive "disposable" system. Our baby is now 14 months and will probably continue to take his bottle for a while. This Klean Kanteen bottle is perfect.. they put a lot of thought into the design of this bottle. The nipple is made so that it will vent the air and it does work. It is even better than the Born Free system because you don't have two extra pieces to wash, just the screw on cap and the silicone nipple which fits inside. Really ingenious, you wonder why all other companies can't make something similar? The Nuk nipples are designed to vent the air also but our baby refused the weird one sided nipple after using the Avent and Born Free type for his whole life. The Klean Kanteen bottle has the option of converting it to a sippy or sports cap for later which makes it a good investment for longevity. I really wish these were available over a year ago because we have probably spent about $250 on bottles, nipples, etc, crazy!!! But of course you will do anything to make sure you child is getting the best. I was quite surprised that these bottles weren't reviewed as I rely heavily on other's experiences. This is a great bottle and so far I can't think of anything it is missing. The cap fits well, the nipple is made well, the bottle itself is shorter and more compact than the Born Free 9oz and I see this as a plus. Nice shape to hold for you and the baby. The bottle can drop and you won't worry. Hands down this is the best.

Updated review: It's been four months since we have had this bottle and we still love it (doesn't leak, easy to clean, nice shape, air venting, etc). Best thing is baby can drop it and no worries (yes, the bottle has a few dents) so he can hold his bottle all he wants. I do have a bit of regret that I didn't know that silicone bottles were available because I am a bit concerned about nickel leaching into the milk. I stopped heating the milk up for this reason. The official website does try to calm your fears regarding this but I would like to see some real data and experiments testing nickel and chromium amounts within the liquid that is being held. My child will probably enjoy his milk from a bottle until he is 2 or so, so I am still considering doing yet another switch :( Thankfully we only use this one bottle so it won't hurt the wallet too much but I have been through so many nipples and bottles it is exhausting.

I bought this thinking it would be a great long-term investment: bottle now and sippy cup later. The problem is that the 5oz bottle I bought does not work with the Klean Kanteen sippy lids. My older daughter has a couple of 12oz Klean Kanteens, so I thought this would be a perfect addition to our collection for our youngest daughter. We'll use this one as a bottle, but after she's finished with the bottle, we're a bit out of luck. I can get the wide-mouth sports cap for it, but those caps make a horrible noise as the child drinks (as we found when we got a sports lid for our other daughter's 12oz sippy cup).

Love these bottles. Super quick to clean because of the wide mouth and shape of the bottle. Short, wide size is perfect. No decorative paint to scratch up. Very easy to mix formula in. I prefer these over the glass bottles that we use as well. I plan on upgrading to a cafe cup lid later for a more cup-like experience while drinking water when my baby is 1+.

HOWEVER I would have given 5 stars if it would convert to a child's sippy. As it is now, we're using these bottles, then we have to move over to a different Klean Kanteen standard adult bottle with a sippy adapter, then back to these bottles with a cafe lid to change it to a commuter. Why is a stainless sippy so hard to find?! If only I could convert this Kid Kanteen to a hard-spout sippy, I'd buy 10 of them without a doubt.

It is perfect for my breastfed newborn. I pump one bottle for my husband to feed her at night and this is perfect. It is a perfect shape for her to latch and it comes out slow, making her work for it and tire her out compared to the medela ones I have that she gulps and is still hungry. I love the quality of the nipple and that its stainless steel and not plastic.

I bought this for my son when he was about 2 months old after wrestling with other leaky and mediocre bottles. It said the nipple was for 6 months plus, but he took to it just fine and has been using it for every bottle feeding since. I just wash it out after he is done, and love the wide neck for washing. After 6 months, 3-4 feedings a day, and now teeth, the bottle still looks new and works fabulously. Absolutely no leaking, easy to clean, and we get lots of compliments on it. My only frustration is now that he can drink on his own there is no way to use it as a sippy cup.
