How many times have you in jest suggested or said give that child some cough medicine for a long flight or to get him to sleep? Well it isn’t a joke some parents have.
If the kids become too much to handle, slip 'em a little cold medicine. It's an often-repeated joke.
One mom, Jill Smokler, said she doesn't vilify parents who medicate their kids: "It's not the end of the world."
Smokler gave her daughter, who was 1 1/2 years old, some Benadryl, expecting her to sleep through a two-hour flight. Her plan backfired– it had an energizing effect on her daughter. The toddler ran through the aisles, talked as loudly as she could, and jumped up and down on her chair. "It was worst-case scenario," said Smokler, of Baltimore, Maryland. "This is what I get for trying to dope up my kid."
