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.
Most women have a 28-day menstrual cycle. That means you have about 6 days each month when you can get pregnant. That includes the day one of your ovaries releases an egg, called ovulation, and the 5 days before. Having sex within that window is key.
