And the winner is....
Technically, it was probably "mommy" but there are a lot of generic sounds that sound like "mommy" and "daddy." But "Cookie" is pretty distinct. So, William's first word. Sigh. What does this portend?
Interesting, and perhaps more disturbingly, I think he is using the word to refer to Cookie Monster, or the trademark sound of said monster, rather than the tasty treat. We have a 'peek-a-boo' soft book of Sesame Street characters he really likes, and Cookie Monster gets the special treatment. Now will will frequently just turn to that page and say the catchphrase himself.
In realted news: we are pretty sure he thinks the sigh for "more" means "grapes" since he is obsessed with grapes and makes the sign whenever he spots them. Still, there are occasions when he signs "more" other than in the presence of grapes. Sometimes he sees something on the table he wants or if he is really enjoying something he is eating. So maybe the sign doesn't mean anything in particular.
Sophie, meanwhile, has become fairly obsessed herself with crime and punishment. The standard punishment for repeatedly ignoring us is a "time out." She is starting to tell us, or herself, when she needs a time out. For example, she will stand up on the couch, and say, "I need Time Out" presumably as punishment for standing on the couch. Sometimes she is a little too quick, and we find ourselves saying, "no no Sophie, it is okay you don't need a time out, just stop." I wonder where this is going though. And where did it come from? I think she does like learning the way things work, and maybe this is her way of figuring out the ins and outs of punishment on her own.
