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.
At What Age Do Babies Start Teething? According to the American Dental Association (ADA), a baby's first tooth often appears anywhere from eight months to a year of age. The last teeth to grow in are usually the molar, or back teeth, which often start making an appearance anywhere from 13 months all the way up to 33 months.
