Flour is the ingredient on which most baked products are based. Flour is made up of starch, protein, sugar and minerals. The protein content decides what the end use of the flour will be. Milk is used in baked products to improve texture and mouthfeel.
Precocious puberty is when a child begins puberty much earlier than the 'standard' age. For girls, this is generally as early as 7-8 years old, as most girls will not start menstruating until 12-13ish. They could then, in theory, become pregnant at that age if sexually active or raped.
Teenage pregnancy is pregnancy in human females under the age of 20. A girl can become pregnant from sexual intercourse after she has begun to ovulate which can be before her first menstrual period (menarche), but usually occurs after the onset of her periods. In well-nourished girls, menarche usually takes place around the age of 12 or 13.
