Mixie Bottle Features
The Mixie bottle comes in 4-ounce and 8-ounce sizes. The smaller bottle holds up to 2 scoops of formula. The larger bottle will hold up to 4 scoops of formula.
You can put these bottles in the dishwasher and in the microwave (although you must be very careful about microwaving bottles because it can cause hot spots that could burn your baby's mouth). The plastic that forms the Mixie bottle does not contain BPA or phthalates, and it is also PVC-free.
The 4-ounce bottle sells for about $19, and the 8-ounce bottle sells for about $22. The nipples come in 3 flow rates for different ages. A 2-pack of nipples costs about $5.
What I Like About the Mixie Bottle
The formula compartment seals up very well. In all of the times I've used it, I have never seen any clumped formula that would indicate it had gotten wet before I opened the compartment. The top of the formula compartment never came open unless I wanted it to. That was a problem for me with other formula container lids that go with other bottles. I've cleaned formula powder out of my purse before when a container opened. It was not pleasant. So, a container that stays closed is much appreciated!
My son has learned that he can push on the nipple of some bottles and get them to leak. He was not able to do that with the Mixie. The nipple did not collapse as he was drinking, which is a major annoyance with some silicone nipples. We never had a leak from these bottles. The lid also stays on very well, even in a full diaper bag.
The Mixie bottle is sturdy. My son is a bottle-thrower. He has managed to break several brands of plastic bottles by throwing them, and those that didn't break often came apart in some way, so the milk leaked out before I could pick them up. I took the Mixie bottle with us on a hay ride, though, and my son threw the bottle off the side of the trailer while it was moving. I went back later, thinking I would find the bottle broken on the side of the gravel road. It wasn't broken, though. In fact, you couldn't even tell it had been thrown from a moving vehicle.
Even though it has the integrated formula compartment, the Mixie isn't much bigger than other baby bottles. I had no trouble fitting it in my diaper bag or in a bottle warmer.
What I Don't Like About the Mixie Bottle
Since there are more pieces, that means the Mixie is a little harder to clean than the standard baby bottle. My dishwasher does a fine job of cleaning it quickly (with the small pieces in a dishwasher basket), but if you need to hand wash the bottle, you'll have to spend some extra time getting a bottle brush into the formula compartment and cleaning the compartment lid. If you want to reload the bottle immediately with formula, you must thoroughly dry the formula compartment first to avoid contaminating or clumping up the formula.
If your baby has trouble with swallowing air, a bottle that requires shaking just before feeding may not be a good choice. Shaking the bottle can introduce air bubbles that are rough on sensitive stomachs. My son did not have any trouble with this as an older infant, but he probably would have as a newborn.
Overall, I love the Mixie bottle. It's a great choice for formula feeding families. If you're willing to spend some extra cash on your feeding system, the Mixie works extremely well.
