Jack Laughlin will start middle school every day with gym class.

What might be a nightmare for other middle schoolers is a dream come true for the 11-year-old Exton, Pa., student and his family. Jack has diabetes and as we reported earlier, he and his parents, David and Cathy Laughlin, argued he needed daily gym classes to recover from his post-breakfast sugar high.

Students at Lionville Middle School usually get gym classes two out of every six days. They spend the rest of their mornings in music and reading skills classes.

School officials initially said there was no compelling medical evidence to rearrange the schedule for Jack and he could get the exercise he needs through a school walking club and intramural athletics.

Now officials have changed their minds.

The Centers for Disease Control and Prevention created this video in which Tracy, a high school basketball player, shares how she was sidelined by a concussion.

Brendan Adams' mother didn't want him to play middle school football. She was afraid he might get hurt.

Wait a minute. Brendan is almost 7-feet-5-inches tall -- the tallest teenager on the planet, according to the Guinness Book of World Records. And she's worried about him getting hurt?

The sad irony is it took a lot of work to get Brendan on the gridiron. His mother's concerns are more than justified. The 14-year-old eighth-grader from Ellensburg, Wash., about 100 miles east of Seattle, has health problems as formidable as his height. His body is full of tumors. His joints are enlarged. And doctors recently discovered an arrhythmia in his heart.

A study presented last week at the American College of Rheumatology's annual meeting showed kids who play video games for more than an hour a day increase their chances of having wrist and finger pain. Among kids ages 7-12 who play up to three hours per day, each hour of play time increased pain by 50 percent.

If a pregnant woman drinks during her pregnancy, she runs the risk of giving her unborn child fetal alcohol syndrome (FAS). Consumption of alcohol during pregnancy does not always lead to FAS. Doctors are unsure exactly how much alcohol can cause problems, but they agree that consuming any alcohol is unsafe. They advise pregnant women and those attempting to become pregnant to avoid alcohol.

When alcohol is consumed, it crosses the placental barrier and can stunt the growth of the fetus. It can also cause atypical facial features (a flat face with narrow eye openings) and damage brain structures and neurons. Permanent brain damage is often common because developing brain cells and neurons become malformed from the alcohol exposure.

As the child ages, he or she can show other emotional, physical, mental and/or behavioral problems. This can cause attention-deficit disorder, poor memory, poor cause-effect reasoning and impulsive behavior.

Unlike at other times in life, the fetal brain is constantly developing, meaning there is no "safe" time to drink alcohol while pregnant.

At 22 weeks pregnant, an expectant mother is in the middle of her second trimester and may start to feel some movement in the womb. The baby is approximately 10 inches and nearly a pound. Her organs are developing at a rapid rate and she may now be moving her limbs and exploring her face. Lips, eyelids and eyebrows are more defined and although her eyes have formed, the iris lacks pigment.

Thanks to a surge of hormones, there are lots of changes for mom too. Her hair is more lustrous and her nails are growing at a more rapid rate. Stretch marks usually appear around this time and skin may take on different textures or shades due to increased melanin. Nipples and areolas often get darker and larger. Some women's feet begin to swell at this point, often going up a half or whole shoe size.

Expectant moms should have had a triple screen test by now, which is a blood test that may detect possible fetal abnormalities like spina bifida and Down syndrome. Next up? The glucose test at 24 to 28 weeks, which checks for gestational diabetes.

When Keith and Brooke Desserich learned their daughter Elena had pediatric brain cancer, they were also told she had only 135 days to live. She made it to 256.

Nearly every day has been recorded by the Desserichs in "Notes Left Behind," a book first published by the family at a small press and sold as a fund-raiser.

Now the book has been republished, this time by publishing giant Harper Collins, and is filled with greater detail. A journal of Elena's last days -- written for her younger sister, Gracie -- the book brings two parents' love for their child from the abstract, unconditional love we all feel, to the simple joy of reading bedtime stories and singing lullabies.

VERDICT ...

Ten months after son Jett's death, John Travolta finally admitted during an extortion trial that the 16-year-old had suffered from autism. Actress Holly Robinson Peete, whose 12-year-old son, Rodney Jr., also has the disorder, says she wishes John had spoken sooner.

"Were there times I said to myself, Ooh, if somebody that A-list comes out, what could he do for the movement? Yeah, I wished that," the former 21 Jump Street star tells Life & Style.

Still, she says, "I don't blame the Travoltas for not talking about it. I would never tell someone what to say about their kid."

Along with her husband, former NFL star Rodney Peete, Holly founded the HollyRod Foundation, which raises money for families dealing with autism and similar conditions. She says it was a family decision for the Peetes to go public with Rod Jr.'s condition, and she hopes John can find solace in doing the same.

"The fact that posthumously he had to say that on the stand, I wasn't glad about it," she says. "But I was relieved he was able to have closure."

Most high school football players would be happy to score a touchdown for their team, but the moment was especially sweet for 16-year-old Tyler Brown of McComb, Ohio, who has been legally blind since birth. According to The Courier, Tyler usually acts as the team's manager, but coach Kris Agle convinced the boy's mother to let her son suit up with the team this season.

The risk factors for SIDS are more subtle and varied than once thought, according to a new study, and may include co-sleeping with a parent who recently consumed alcohol.

The study, published in the British Medical Journal, followed all babies born in a southwest region of England from 2003 to 2006, in order to identify common circumstance and behaviors involved in SIDS deaths. ABC News reported that researchers found a higher SIDS risk when babies are co-sleeping with a parent who had recently consumed alcohol.

An unusual relationship between a 12-year-old musician and a cancer-stricken 4-year-old is helping to raise awareness of a rare form of childhood cancer.

Anyone who's lived in or visited a big city knows that street performers, or buskers, can be found on every corner -- you stop and listen, and toss a few coins in their guitar case. But Abby Miller stands out, and not only because she's just 12 years old.

Abby takes her music to the streets to raise money and support for her 4-year-old friend, Taylor Love, who suffers from a little-understood cancer, neuroblastoma, which attacks the central nervous system. According to a story on CNN, Taylor is in remission now, but the disease has a very high risk of recurrence and there is little research on the illness.
