So, I realize that having a formula mixer might sound like the epitomy of laziness. How hard is it to shake up a bottle? I picked up this gadget on a whim, but I have to say that I love it! I usually put the formula in the bottle first, pour water in next, and then mix it with this tiny blender. In just a couple of quick seconds, the formula is totally mixed, with minimal bubbles. For me, that is the best part. If you shake to mix formula, it creates a ton of bubbles which can cause gas issues for the tiny one.
This mixer is tiny, lightweight, battery operated (2 AAA), easily cleaned, and quiet.
I am using small bottles right now (4oz) and this mixer is a good fit. I don't know how well it will work when we move up to a larger size, but for now, it is perfect!
