Babies Don’t Find Yawning Contagious
By Kaye Nemec
You’ll probably find yourself yawning throughout this post. For adults, talking about yawning, reading about yawning and watching someone yawn is oftentimes contagious. In fact, at least 50% of adults will automatically yawn if they see another person yawning.
But this contagious behavior does not develop in children until around the age of five. Before age five babies will yawn as a sign of tiredness, but usually only a couple of times per day. On average, adults yawn seven times per day.
In the study performed by the University of Stirling, mothers reported that their babies did not respond to their yawns by yawning. Toddlers who watched a video of people yawning also did not respond by yawning.
Once children reach twelve years old they have usually transitioned into the contagious yawn stage and have a tendency to yawn contagiously as frequently as an adult.
