Sariray,
You have the luxury of living in a world that , because of vaccination, has not known the impact of widespread disease. Go to any Jewish cemetery that dates back to the 1800’s ( like Washington Cemetery in Brooklyn). What you’ll notice is quite a few tree stump monuments. Those are graves of children. My father in law lost 3 siblings who died of diseases that are preventable today. Until the Salk and Sabin vaccines for polio were developed, thousands either died or were paralyzed annually. When Salk asked for volunteers to take the vaccine, the line of mothers and children was almost a mile long. You live in a world made safe for children by vaccinations
