Can you tell we just got back from the DAN this morning???? So for the second question.... Has anyone gone through B12 shots? difficult child is so deficient in B12 that they were really pushing the shots vs the supplements. The kicker is I have to give them to her I did read they are much more effective than the supplements buttttt gosh poor difficult child has anyone been told of a very bad B12 deficiency... did you do shots??? Help... I just always second guess my decisions when I know how hard it is going to be on her.
