Mixie Baby is a formula mixing baby bottle which provides a way for a tired parent to feed a hungry baby in the middle of the night. Once the bottle is prepared, there is no need to unscrew the bottom and reattach it to the bottle. With Mixie Baby, you merely push the button on the bottom and it releases the formula, utilizing the formula compartment lid as a free-floating agitator to break up clumps and provide efficient mixing. Its convenient all-in-one design holds formula and water, making it ideal for nighttime feedings, air travel, road trips or dining out. It reduces clutter in the diaper bag and eliminates wasted formula. Less mess, easy to clean.
