(NEW YORK) -- Children under age five make up most of the 100,000 Americans treated in the emergency room after accidently swallowing medications, according to the Substance Abuse and Mental Health Services Administration. And about 90 percent of child poisonings happen at home, according to the Consumer Product Safety Commission.
The poison can turn out to be any common household product children can get their hands on, according to Dr. Kevin Osterhoudt, emergency medicine pediatrician at Children's Hospital of Philadelphia.
"Children are curious by nature," said Osterhoudt. "The most common things are things they find in the home -- cosmetics, cleaning substances, but also our medicines and pharmaceuticals in the house."
ABC News' senior health and medical editor Dr. Richard Besser tested three different types of medicine containers among six toddlers, to find out how fast they could open the containers. All six of the kids were able to break into the flip-top medicine containers -- some kids only took 10 seconds to open them. Four out of the six kids got into the easy-open bottles in less than 30 seconds. None of the six were able to open the child resistant prescription bottles, however. But that doesn't mean it can't be done.
