A high pressure system has higher pressure at its center than the areas around it. Wind blows away from high pressure. Winds of a high pressure system swirl in the opposite direction as a low pressure system - clockwise north of the equator and counterclockwise south of the equator. This is called anticyclonic flow. Air from higher in the atmosphere sinks down to fill the space left as air blew outward.
Most babies get their first tooth at around 6 months, but your child's chompers may appear as early as 3 months or as late as 14, depending on such factors as when Mom and Dad started sprouting teeth and whether or not your baby was a preemie (preemies tend to teethe on the late side). How babies experience teething can vary widely, too.
Starting at around 3 months of age, infants begin to show outward signs that baby teeth are coming. They produce more saliva and will put their fingers in their mouths. This drooling can go on for several weeks before you'll see a tooth. Infants typically get their first tooth between ages 5 and 12 months. The bottom incisors emerge first, followed by the top incisors. Usually around 2 years of age, a toddler has a full set of teeth, explains Dr. Edward Kulich of New York, NY.
