Why is birth weight plotted on a bell curve?

Dr. Mehmet Oz, MD
Cardiology (Cardiovascular Disease)
The classic bell curve helps make a vital point about how your baby's weight in the womb influences his lifelong health. Most times, kids fall in the middle of that bell curve—right in the normal range; that's why the middle of the baby-weight bell curve is bigger than a septuplets' grocery bill. But you also need to be aware of what happens when you teeter toward the extreme edges of fetal weight, because that's when your provider may need to intervene.

In pregnancy, the bell curve teaches us about what's happening to your developing baby. Your baby's optimal grade rests right in the middle of the bell curve. Why? Because Goldilocks was right about your baby's size. You don't want too big and you don't want too small. You want just about right.
