The geodesic may be plotted on a gnomonic map, and later transferred to a Mercator map and split in loxodromes piecewise. This projection was possibly first used by Etzlaub ca. 1511; however, it was for sure only widely known after Mercator's atlas of 1569.
When your child has topped 20 pounds and/or one year, she can ride in a forward-facing car seat. Of the states establishing guidelines, Florida has the youngest age limit of 3 for securing your child in a forward-facing car seat. Several states mandate the highest age limit of 8 years old.
If a booster seat has a minimum weight limit of 40 pounds, you can't legally put a 30-pound child in it if your state has a proper use clause. If an infant car seat has a maximum height of 30 inches, it would not count as a legally appropriate car seat for a 34-inch long baby.
