What would cause a babies head to grow at a slow rate?

Family trend?: Small heads can be a normal family trait. So can large heads. Head growth is a measure of brain growth, but is not a measure of brain function. Some babies have smaller heads but are very smart and healthy. Your pediatrician will carefully monitor growth and development. Any problems can be dealt with in an appropriate manner.

Head growth reflects: brain growth. Unless an infant has had an infection or trauma, we look for genetic & other medical causes of prenatal origin if 3 measurements done the same way by the same person over 3 mos. show lack of normal velocity of growth&/or development is delayed.
