I Need a Nap!

While sleep studies typically focus on adults, a study in the Journal of Sleep Research by Berger and colleagues looked at 30-36 month olds.  They studied ten healthy children with no assessed sleep problems and looked at the impact of missing one nap.  Parents kept a strict sleep schedule for the toddlers for five days, at the end of which they either allowed or did not allow the daily nap.  They then repeated the same strict sleep schedule for five days and did the opposite nap arrangement (i.e., nap or no nap).
