Children come in all shapes and sizes, and all babies grow at their own pace. At your pediatric visits, your healthcare provider will plot your child’s growth on a growth chart to make sure your child is on track. The chart may seem daunting, but your doctor can help you understand this useful tool and what the results mean for your child.

The height of a child is measured from the top of the head to the bottom of the heels. The height of a child under 5 years old is measured when the child is lying down, so it is also called length. The average height of an 11-month-old boy is 74.5 cm while a girl of the same age is about 73 cm. Therefore, an 11-month-old baby of 70 cm is below the standard reference value.
