Kyle Kumpf wrote a post on LinkedIn about how he applied Lean in his household, since they have food allergies and restrictions. If the wrong child drinks cow milk, they are going to be in for a very unpleasant time.
To prevent this from happening, the cup of a different color always has the almond milk.
The longer term solution is to remove dairy from the house, but it will take him time to accomplish that.
