Iíve got a five week old daughter who yawns. When she yawns he yawns as well. When he yawns she doesnít yawn. Is the contagious yawning thing learnt or a cultural thing?
Thatís a very good question. Yawning is a really common reflex, actually that happens in lots of different animals. If you see someone yawning you want to yawn yourself which is very strange. We see it in all these animals including some that maybe arenít so social. Maybe it isnít something thatís learned but maybe a bit more inherent. Perhaps it just starts to arrive at some point.
Often with very young babies, their eyesight isnít very good. They canít focus very well so it could be just she canít see you yawning. She doesnít learn how to yawn from that.
