seeing ,hearing ,or even reading about some one yawing can trigger a yawn in your brain
When a child sees someone yawn, the brain first recognises the other person’s facial movement and social cue. This involves networks responsible for social perception, attention, imitation and emotional processing.
What makes this especially interesting is that contagious yawning develops during childhood rather than being present from birth. That suggests it may be influenced by brain development and our growing ability to respond to other people’s actions and social signals.
Researchers have also explored whether contagious yawning is connected with empathy and social bonding, although the exact mechanism is still not fully understood.
So when your child yawns because you yawned first, it isn’t simply imitation.
It is a small, everyday example of how the developing brain observes, interprets and responds to the people around us.
