3 year old with mild bowing tibias and pain. vitamin d level of 4. ped reports history and labs consistent with rickets. what do i do from here?

Pediatric specialist: As children in the U.S. have easy access to vitamin D in the diet or in children's vitamins, and because sunlight is ample in most of the U.S., rickets is rare. When a child has rickets, pediatric specialists at a children's hospital can look for rarer causes of rickets such as genetic or hereditary disorders, liver or kidney problems, intestinal absorption problems like celiac disease, etc...

Vit d deficiency : Wow that's a pretty low Vit D level. Start at least 1000 IU Vit D daily . May poke the gel gap with a needle and mix in food for now. You need to see a pediatric endocrinologist ASAP and the work up should include Celiac disease as well. Good luck
