Thanks for the info. The nuerologist had mention blood work but wanted to wait until she was older. I am going to go ahead and request that he does it now. I also had wonder about iron deficiency. I have read where B12 and iron deficiency can be related and also can have some of the same symptoms. Iron Deficiency can also cause sleep disorders and restless leg symdrome. She has oral aversions due the SPD. So I know she does not get adequate nutrition(I do supplement w/ formula and multi-vitamins). I was also was anemic while pregnant and brestfeeding. It has been so frustrating because of her age it took a while to get the Dr's to listen. 15 months of knowing something was wrong. It took me having a break down to get their attention. I feel we still are not there but I get it is progress. There new symptoms are just concerning because they are progressing so rapidly. Poor baby has slept in 15months. I know it effects her development. At this point she has no delays and actually has meet all her milstones early. She just has behavorial issues at time.
She does have issues w/ socks actually anything on her feet. Blankets are her enemy.
No rashes except the chafing were she is rubbing her ankles together. She goes bare footed alot. I use steam to clean the floors. I use dye/fragrance free detergent and soaps. So hopefully that is not the cause. She did get a new pair of shoes but she had started rubbing them before then.
I also notice alot twitching in her legs and hands especially while she is sleeping.

Thanks. Anymore info is much appreciated
