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.
Once your child outgrows their car seat, they'll need to switch to an appropriately sized booster seat. It's recommended that your child remain in a booster seat until they're at least 57 inches, usually between the ages of 8 and 12.
