A tired kid is a cranky kid, but getting your toddler or preschooler to go to bed on time can be a challenge (second only to getting them to eat veggies!). The solution? New research suggests it could be changing what your child is watching on TV.

A recent study from the American Academy of Pediatrics found that violent, or age-inappropriate, television shows can have a negative affect on children’s sleep. (And “violent” doesn’t mean your kid is watching Die Hard.) In the study, the Seattle Children’s Research Institute evaluated the sleep and TV-viewing habits of 565 children ages 3 to 6. Half of the children replaced their regular TV shows with safer shows (such as Sesame Street and Dora the Explorer), while the rest viewed their normal programs (which included SpongeBob Square Pants and Scooby-Doo).

Prior to the experiment, parents completed questionnaires regarding their children’s sleep habits. At the time, researchers saw no difference. Parents filled out these survey again at the 6, 12, and 18-month marks, reporting their children’s night wakings, nightmares, trouble waking in the morning and daytime tiredness.

At the end of the study, researches found that those who viewed more educational programming were 64 percent less likely to have trouble falling asleep. Researches saw that the most common problem was difficult with sleep-onset latency, with children taking over 20 minutes to fall asleep. Children also experienced difficult staying asleep and occasional nightmares.

Switching shows may offer more than bedtime benefits. Michelle Garrison, lead author of the study, says the safer shows also act as educational tools. Wondering what “safer shows” means? In the study, that meant a “rating of TV-Y, being rated high on educational and/or prosocial value by CommonSenseMedia.org, and being currently available on network
or cable television… Representative recommended shows included Curious George, Sesame Street and Dora the Explorer.”

“These shows can be beneficial for preschool children to watch, because they emphasize things such as literacy, numbers and social skills,” Garrison told HealthDay. Garrison also adds that just because children can benefit from a show, parent should still “power down” about an hour before bedtime.

Do certain shows affect your child’s sleep? What do you consider “too violent” for your little one?

How Much TV Should I Let My Toddler Watch?

We’re excited for the season five premiere of Mad Men on Sunday. The show is too addicting, plus, who wouldn’t feel better about their own parenting style after watching Betty Draper’s Worst Mother of the Year act. The actress who plays her, January Jones, who’s a real-life mom herself, told People that she and Betty have completely different parenting styles: “What’s nice is that the expectations for my parenting is very low, so I can really only exceed expectations.” And while she says she’s nothing like Betty, January does stand up for her character. She told The Daily, “All of her actions are justified. Her husband’s cheating on her and then she find out that he’s not who he says he is. That probably warrants a divorce. And, you know, Sally shouldn’t be masturbating at other people’s houses or she’s going to get slapped.”

Well, we understand January’s need to defend her character, but we still think Betty’s crazy. We’ve rounded up some wild motherhood moments from Mad Men:

-Betty and Don Draper’s daughter Sally cuts her hair while she’s staying with her father. When Don brings her home, Betty asks Sally to take her hat off and how does she react? By slapping her daughter.

-Sally’s caught masturbating at her friend’s house. When Betty finds out she asks her daughter, “What’s wrong with you?” then later on, takes her to a therapist. What happened to having a good old fashioned talk with your kid before sending them to a shrink?

-Betty drank and smoked during pregnancy. Okay, we get that it was considered no big deal back then, but still.

-Betty abruptly fires her long-time nanny, Carla, because she let a kid, whom Betty hates, say goodbye to her daughter. Sad, since the kids were really close to Carla!

-Sally runs away from home and goes to her dad’s office. When Don asks Betty to pick her up, she refuses and basically says, “Who cares,” and tells Don she’ll pick Sally up the next day. Don and Sally actually have a nice time together — they go to a museum!
