How much blood does a 6 year old child have?
(4.4 to 5.4 kg). By the time they’re 5 or 6 years old, children have about the same amount of blood as adults do. But because children are smaller and their bones, muscles and organs don’t weigh as much, their blood makes up a larger percentage of their body weight than it does in adults, Landau said.
How many units of blood does a child have?
The amount of blood in a person’s body depends on their size (the bigger the person’s body is, the more blood it will contain). A newborn baby’s body will contain only around a cup of blood whereas a 150-180 lb. adult will have approximately 1.2-1.5 gallons (or 10 units) of blood in their body.

Why is blood loss in children worse than adults?
The higher metabolic rate results in greater consumption of oxygen and other metabolites, and for this reason, higher respiratory and heart rates. The larger surface-area to body-mass ratio results in greater heat loss for infants and children.
