As parents we feel guilty now and then about what we should/could have done otherwise. I felt guilty when my son injured himself at 5, leaving a notable scar on his nose. I felt guilty when he was found out nearsighted at 10 and would have to wear glasses because I had been wearing glasses since my teenage years. I felt guilty when he started to experience migraines at 12 because I had had migraines since long time ago. I felt guilty when he was tested PPD positive at 17 due to his BCG vaccination taken in
