I have a new client who is 4 years old.  I brought him from his class into the therapy room one day this week and started making my best efforts at making a session full of articulation practice fun ("Say the /k/ sound."  Try again-use the back of your tongue.  You said the /t/ sound.  I want to hear the /k/ sound.  Try again, please."  On and on, the same sound, over and over again).  He tried a few times, then decided to lie down on the mat.  I said, "Naptime is all done.  Why don't you want to get up and play with me?'  He said "Du wame."  I asked, "What did you say?"  He said, "Dis du wame."  Yes, according to my best clinical judgment, I'm pretty sure he told me my therapy was too lame!     

Next day-same kid.  He's also working on the /g/ sound.  So as he drove a rocket around the table, occasionally crashing into a Tarzan doll, I modeled the word "Go!"  Instead, he said "I tid him in da nuts."  I'll let you translate that one.
