Advice on baby naturopath / nutritionist

Hello, I am looking for a naturopath or nutritionist that specializes in babies. My baby has a high lead level but not high enough to treat medically and the doctor said to do nothing and just wait for it to go down. I would like to take a more active approach and understand that there is a natural way to remove heavy metals from the body with a heavy metal elimination diet and I'm hoping to find someone to provide guidance on this. 

Thank you so much for any recommendations.
