How can families prepare for a sleep study for a child?

How can families prepare for a pediatric sleep study? Here is a nice site.
Make sure that you are going to a center specializing in children. It makes a difference in the data collection, analysis, diagnosis and treatment. My protocol (learned from doing EEG's all the time) adds some developmentally sensitive elements and gets 92% success with kids.

I recommend that kids and parents make it a fun night, since typically the parent will be sleeping in the room with the child. They can wear matching pajamas, order take out food, and stay up as late as they like. This helps take the pressure off the child falling asleep since the sleep study is to find out what happens during sleep. The children typically sleep better than the parents do.
I also tell children the same rules apply in the sleep clinic as in their home; if they’re able to jump on the bed at home they can do it here. I encourage them to bring anything from home— except their pets—to make them feel comfortable, such as pillows, blankets, and sheets. We also make sure the clinic is very child-appropriate with video games, magazines, and telephones for the child to call home if they want to.
