Yes, we did get sick. Our parents bought all sorts of patent medicines in an attempt to cure us. Very few did any good. Some contained alcohol or other dangerous drugs, but mom and dad didn't know this, because there was no requirement yet that such ingredients had to be listed on the fancy bottles in which medications were sold.
Fortunately, a few of us survived in spite of our medications and went on to enjoy peaceful, healthy sleep interrupted only by the family dog.
