Erica Brown called 911 for two days before a helicopter finally spotted her, trapped in her Houston home with her 7-month-old son and three other children. Sometimes when she called, she got nothing, just a busy signal and a disconnection. Multiple times she was told that they'd try to send help. Hours would go by with no rescue.

The family spent two nights in their trailer watching the floodwaters from Tropical Storm Harvey rise up the foundation. "It was a hard feeling because I thought me and my kids were going to lose our life in this hurricane disaster."

Well-trained guide dogs are important for visually impaired people who rely on them. But many puppies bred to be guide dogs flunk out of training programs.

A study published Monday in the Proceedings of the National Academy of Sciences suggests the way a puppy's mother raises it may be the key to the dog's success, or failure. A research team at the University of Pennsylvania found that puppies destined for guide dog training are more likely to fail if they're coddled by their mothers.

The first problem with the airplane bathroom was its location.

It was March. Greg O'Brien and his wife, Mary Catherine, were flying back to Boston from Los Angeles, sitting in economy seats in the middle of the plane. "We're halfway, probably over Chicago," Greg remembers, "and Mary Catherine said, 'Go to the bathroom.' "

"It just sounded like my mother," Greg says. So I said 'no.' "

Mary Catherine persisted, urging her husband of 40 years to use the restroom. People started looking at them. "It was kind of funny," says Greg.

"They're not gonna want me to play 'babies in space'," says Greg O'Brien. "You know, where I pick 'em up in my hands and I swirl them around over my head like a rocket ship. I always say 'Babies! In! Spaaaaace!' "

It's October 2016, and he is musing about the latest O'Brien family news. His daughter, Colleen, is due to have a baby in November, and ever since he found out, Greg has been struggling with competing emotions.

Diagnosing attention deficit hyperactivity disorder can be difficult. The symptoms of the disorder, as defined by the Diagnostic and Statistical Manual, or DSM, have changed multiple times.

Even if you know what to look for, many of the symptoms are pretty general, including things like trouble focusing and a tendency to interrupt people. Discerning the difference between people who have a problem and those who are just distracted requires real expertise.

Twenty percent of children who were in a car crash where someone died were not buckled in properly or were not wearing a seat belt at all, a study finds, as were 43 percent of children who died themselves.

And child fatality rates in deadly car crashes vary widely by state.

Inflatable beds can be cheap, which is good news for consumers who want an alternative to pricey traditional mattresses. But their uneven, soft, impermeable surfaces are dangerous for babies, and can increase the risk of sudden infant death.

The dangers may be particularly acute for low-income families, a recent essay in the American Journal of Public Health argues.

Researchers in Germany have found that getting drunk is associated with abnormal heart rhythms.

Their study was conducted in a place teeming with potential research subjects.

The Food and Drug Administration says children under 12 should not be given prescription medicines that contain codeine or another narcotic, tramadol, and that such drugs can also be dangerous to youth between 12 and 18.
