Interesting. I can look back and see a couple autistic signs from birth BUT he kept getting sick at his pediatrician’s office and by 18months I moved him to a regular PCP. He had had several ear infections and respiratory infections and the ear infection at around 9 months seemed to really change him – he couldn’t get “well” and around 2 years old had 2 severe bouts of RSV – I try to stay away from antibotics since I’ve worked on a more holistic management with my son. I do think that vaccines were also a contributing factor being that his immune system was not up to par and POSSIBLY had autoimmune issues which are never tested for prior to vaccines.
