For instance, 1 month ago a scenario would play out where he would start screaming suddenly and for no discernable reason. I would ask over and over what he wanted. I would volunteer objects. I would carefully check the big 3: tired, hungry, wet. If I didn't get lucky and happen upon the desired item (one time it was a tiny plastic cat sitting in a high windowsill) after kicking and hitting attempts, he would simply scream himself out. Now just a month later, he can easily just tell me what he wants but if he gets too hungry and starts to head down this road I say,"Button can you point to what you want?" He will then point at the object. If it is a word he knows like "truck" I will say, "Can you ask nicely for that truck?" and he will say, "Peas tuck." If it is a new word we will practice that word once and then he can play with the item.
His ability to express himself and to understand us has released so much fear from our beautiful little boy. Don't get too excited here, but sometimes he will even play with his car in the hallway and allow me to go into the potty-room alone...if I leave the door open and if I sing the whole time. Baby steps, folks, baby steps.
