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.
Women can get pregnant on their period. Women who feel frisky and have sex on their period should keep in mind they can still get pregnant. Women who have typical 28- to 30-day or longer cycles are less likely to get pregnant, since ovulation is several days away, decreasing chances of conceiving during this time.
