Hi , it is very frightening to have a baby who appears to not be well. I hope you can find some help for him and you.
You have put your question on the forum for Multiple Sclerosis, which is a disease of the central nervous system and rarely affects young children.
I'm sorry but I don't think we will be able to help you with your question.
You might want to try one of the other forums here, such as
the forum for pediatrics (children)
good luck with finding answers,
