Yawn, baby, yawn…

At what point can a toddler see someone yawn and have to yawn in return?

Yawns are infectious. There is no denying that you cannot see, hear or even think about yawning with out yawning back. (Have you yawned yet reading this? – if so, you can’t help it! It’s built in to us!) But what I want to know is… when does this sleepy curse kick in?

 

My daughter is 17.5 months old. I can yawn all day long and she doesn’t even flinch. Not even a tiny hint that she is fighting a yawn away. However, she does one yawn and poof, suddenly that power takes over me and I can’t stop myself!

Yawning is not something we choose to do. We don’t sit there and think ‘oh, I’m tired. I think I will yawn to prove it’. It is a natural thing. I don’t even know why it is a thing we do. What is it about being tired that forces our mouths to open unattractively, force an eye to close (like Cleo demonstrates above) and occasionally have a random sound at the back of our mouths? What about that screams ‘BEWARE, TIRED PERSON!’ It’s so weird!

But if it is such a natural thing… when do toddlers get this milestone? I will continue with this randomly daft experiment and get back to you!

(btw… I don’t know about you, but the word ‘yawn’ has lost all meaning in my head now. And I’ve yawned about 20 times since I started writing this…)
