Cracking the Code

So Bug like a lot of kids with autism, will repeat syllables over and over again.  When he is doing it, he likes you to copy him.  I always thought in his mind he is saying something, I just didn't know what it was.  For the last year  he has been doing this same one where he says, "dudduhduh huh wadah."  I know it well because I've had to say it with him so much.  Monday night I was at my parents house, and he started to say it again, but this time he added at the end, "Winnie the Pooh."  I knew he had to be singing a song about Winnie the Pooh, and I look down and he is playing with an Eeyore stuffed animal.  And then it clicked!  "duhduhduh" translation, Deeping in the "huh" hundred acre woods "wadah" where Christopher Robin plays.  He was so excited!  He had this sparkle in his eye that said, "You understand me!"  It was so precious having the moment of recognition in his face.  He wanted me to keep singing it with him.  When we got home that night, I wanted him to sing it for Hubby, but he said "No, night night."  We are going to have to get working on the next code!  It starts with "yaha".  Any guesses?
