4 year oldest memory

My mom was in the hospital so I was staying with my aunt on their dairy farm. 1948. I was walking weirdly and holding my head. My aunt asked what I was seeing. I told her about little fairies in my eyes. Since she had migraine she took me to the family doctor. He knew many extended family members and diagnosed migraine. I'd already vomited in his office. There wasn't much to prescribe back then but he had me drink a special tea. I can remember being wrapped in sheets soaked in Epson Salts. I'm 82 now chronic but the medication is so much better.
