The name malachite derives from the Greek Moloche meaning mallow, because the stone is the same color as mallow leaves. Malachite is copper based, and has been crushed and used as pigments for thousands of years.
Booster seats are for children who have outgrown convertible or toddler seats. Booster seats are for children who are 4 to eight 8 old, weigh 40 to 80 pounds, and are less than 4 feet, 9 inches in height. You can use a booster seat until an adult seat belt correctly fits the child without use of the booster seat. Always use both the shoulder and lap belts with a booster seat.
Many booster seats wouldn't be appropriate for a smaller toddler because of the minimum height and weight. While some high-back booster seats have a minimum weight of 30 pounds, there are lots of other booster seats that require a child to weigh at least 40 pounds before use. From a practical standpoint, parents tend to have an easier time keeping their child in the harnessed car seat altogether.
