My son(20 months) still has his anterior fontanelle open(about 2cm) and is short for his age. He walked relative late 18months. I myself have had my vit D checkt last week: it was 22 ng/ml. Reading on this website im now very worried that my son has Rickets:(.
From birth I gave my son vitamin d (400IE/day)
Should I test my son on vitamin D? But drawing blood from such a little boy seem like a heartbreaking event… Is there a less invasive way to know? Am I "seeing things"?
