Aidan's learned how to play chase. I've been trying to teach him this game since he could crawl. Only this last week has he mastered the basics though he still doesn't quite understand all the rules.
He understands that if he runs away from me I'll chase him, eventually catch him, and tickle him. (That last part is his favorite.) However, if I try to walk away, he starts to cry as if he thinks I'm leaving and don't want to play anymore. Instead he wants me to stand next to him until he's ready to run away and then have me chase him.
I've tried to explain to him the game is more fun for everyone when I start to walk away then turn around and chase him.
"Gah goo ah dada!"
One step at a time, I guess.
