You need MILKSCREEN because you don’t know how to stop at that first beer/wine spritzer/shot of tequila. Photo and blurb from am @ zon. com…. Seriously, just say no!
From the Manufacturer
In just two minutes, milkscreen quickly and accurately analyzes breast milk for alcohol. Every mother is unique so, naturally, the way our bodies metabolize alcohol is unique, too. Metabolizing alcohol depends on several factors including body weight, type of alcohol consumed, and food intake so milkscreen was created to eliminate those variables. milkscreen also helps ensure that the alcohol concentrated in Moms breast milk is not at a level that may have negative impacts on Baby. Studies have shown infants consuming breast milk with alcohol concentrations at approximately 30mg/dl, or 0.03%, and higher have exhibited distinctive changes in feeding behavior and sleep. Babies consume less if the milk contains alcohol and they also sleep less and wake more frequently. We have set the milkscreen test to show a color change at 0.02% to help Mom stay within recommended feeding guidelines.
