Thanks! You’re right… Here’s the AAP guideline – http://pediatrics.aappublications.org/content/122/5/1142.full
Here’s the revised version:
EXCLUSIVELY BREAST FED BABIES
In exclusively breast fed babies, look for Vitamin D and Vitamin K deficiencies.
PEARL: ALL BABIES/KIDS are now supposed to get a total of 400 IU (international units) of Vitamin D per day in their diet. For formula fed babies, this is usually attainable through the formula. Breastfed babies need supplementation.
PEARL: Patients with CF (CYSTIC FIBROSIS) or RICKETS need > 1600 IU per day!
