You might not have heard of vitamin K — but it's important
The Galveston County Daily News, March 15, 2022
Vitamin K doesn’t cross the placenta, so babies are born with very little vitamin K in their bodies. To complicate their low levels, breast milk is low in vitamin K, Dr. Sally Robinson writes in her regular column. Since 1961, the standard of care is for newborns to receive one shot of vitamin K to prevent those complications. However, in recent years there has been an increase in the number of parents who refuse the intramuscular shot.
