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.
The average child gets his first baby tooth at age six months and then gets three to four new teeth every three to four months. This continues until the second molars erupt at about age two to two and a half years, at which time your child should have all twenty baby teeth. If your child got his first tooth early or finished getting all of his baby teeth early, then he might start losing his baby teeth early too. On the other hand, if he didn't get his first tooth until age twelve or fifteen months, then he might be a little later than average in shedding or losing his first tooth.
