Neila, I am sorry that I did not see any of the messages until just now. Please post in the regular forums or private message to me. I do not regularly check visitor messages. I am very sorry to hear about your baby. I don't know what to suggest to you. It seems to me that he has more than just meconium aspiration. For example, the presence of microcephaly and such severe loss of white matter suggests that your baby has a genetic disease that is responsible. I am not an expert in developmental conditions of babies but a number of diseases such as Krabbe disease may manifest in symptoms that you describe. I am very sorry that I can't be more helpful. Wise.
