Today something clicked with Reuben...

And for the first time, he

... patted his diaper upon hearing the word, a gesture which is close to the ASL sign for diaper
... clapped his hands and then kept clapping
... signed milk (we've been working on this one for months!)

His OT acknowledged, finally, that his standing up is not a reflex, but a controlled movement, sit to stand and sit again.

Hot off the press: Last night, whilst I was having a lie down waiting for the rascal beside me to fall asleep, I looked in amazement as Reuben sat up in bed for the first time and looked around quite bewildered, or was it rather chuffed at his own achievement? He knows he's doing great; he sucks up the applause as if he were Diana Ross on stage.
