The 2nd house is the house of food, speech, and accumulated wealth. The Moon (Chandra) represents the mother, emotions, and specifically, milk.
When the Moon sits in the 2nd house, it creates a very specific dietary preference. Dr. Rishi Rohit Sharma reveals this classic Lal Kitab *Nishaniya*: This person will have a deep, natural craving for milk and dairy products ("doodh peene ka shaukeen").
This is actually a subconscious remedy. By consuming milk, they are strengthening their 2nd house Moon, which in turn brings them emotional peace and financial stability. If you have this placement, never stop drinking milk!
