Baby foo is any food that is given specifically to infants, roughly between the ages of four months to two years. The food comes in multiple varieties and tastes, can be produced by many manufacturers, or may be table food that the rest of the family is eating, mashed up. A common trait of the many different baby foods is that they are designed for ease of eating; either a soft, liquidy paste or an easily chewed food. This is because infants lack teeth and experience in eating.
