Our baby had skin problems around all joints, neck, etc and major gastric reflux problems, always crying and could not sleep long. After a year we got some advice to remove any product with lactose in it. My wife breast fed so my wife stopped having any dairy products, etc. Basically anything that may have lactose. Within a week, the skin and restlessness cleared, about two weeks our baby daughter slept without problems and just about all the skin was clear. Today she is 9 years old and still does not drink milk or similar things as she still will break out into a rash but nowhere near as bad as when she was a baby.
