Craniotabes is a skull condition characterized by thin, soft areas, and it has recently been defined as the earliest sign of vitamin D deficiency in newborns. It may signal impending rickets, but until recently, it was considered a physiological anomaly needing no treatment. Obviously, any newborn diagnosed with craniotabes should be immediately checked for vitamin D deficiency to avert full-blown rickets.
Remember that it is virtually impossible for a newborn to be vitamin D deficient if the mother’s blood is replete with vitamin D. And as we have already discussed in a previous post, it is imperative that a woman who is breastfeeding take in 6,400 IU of vitamin D3 daily in order to maintain optimal levels in both herself and her infant.
Moms, you are responsible for the health of your infant; you need sunlight or supplements. Act now!
