Launched in 2012, Mixie® is the worlds first 2-in-1 formula mixing baby bottle; it is the first formula baby bottle that can be fixed now and mixed later, making baby happy and life easier for parents and caregivers. The Washington-based company created the unique and now-patented baby bottle with a formula compartment that is cleverly housed inside the bottle; since the bottles are the same size that consumers are already used to, its easy to transition and great when you are asking a babysitter or caregiver to feed your child since you can prepare the formula in advance all they do is press a button and shake the bottle to blend. The company makes innovative formula-mixing baby bottles, available in both 4 oz. and 8 oz. sizes along with 3 stages of colic-minimizing nipples; the dishwasher and microwave safe products are BPA, phthalate and PVC free so you can enjoy ease of use and peace of mind with a smart solution that satisfies everyone.
