gulp aaahhhh

Torben wanted a drink this morning and I told him he needed to ask. He's pointing and grunting and again I tell him "What do you say?" Then he points to the glass and then in his mouth. So again I let him know, again, words need to be used. So this time he does that sound that you know you do after you take that first drink of pop, or whatever when you are really thirsty. Gulp aaaahhhh. and then he does say drink and then does the sign for please and actually said it very quietly too. (We have been trying to get him to say it out loud when he signs it too.)
But the sound thing was not what I expected at all. It was pretty funny. He does do it after he drinks but to do it as a way to get a drink, that's great!
