Yawns are in fact contagious as it is a subconscious effect of our mind. When yawning we gain more oxygen then we would breathing.

When the brain thinks that there is a lack of oxygen in a given space, due to the other person yawning, and you do as well, you are effectively trying to steal the oxygen from the other person to ensure you live. This also explains why dogs will yawn when a human does, and vice versa.

Why is it when you yawn your daughter acts really weird?

Exactly how weird, and for how long? It is possible that you are unaware of something really odd or funny about your body movements or vocalizations when you yawn, and your daughter's weirdness is an attempt to stifle a reaction that she thinks might embarrass you. If that's the case, you have a chance to bond a little, have a laugh and a yawn or two, and maybe learn to yawn in a less, well, gaping manner? For some reason, your question really gives me a weird urge to see you yawn.
