I agree with Lynn. The treatment needs to come ASAP. I'm so sorry :'(. He needs calcium with vitamin D on his food every night until symptoms resolve and still amphibian multivitamin powder on his food one day a week. He needs a vet for a proper injection ASAP. No doubts on this one.

I hope this helps. Please keep us posted. We will help as much as we can but your baby needs more help than you can provide at this time.
