Do babies have big heads or short arms? Elijah can barely touch his hands together over his head. So does that mean that his arms are too short and will grow longer as he ages or that his head will shrink relative to his body?
The answer is that babies have proportionally bigger heads than adults. A child’s head makes up 20% of their overall height while an adult’s head is only 11% of their height. That means that if our proportions didn’t change as we moved through our lives, my head would be roughly twice as big as it is now!
