Liam has discovered the power associated with the word "no". About 3 days ago, he started saying it. Now he repeats it and shakes his head when I ask him to do things. It is still cute. I'm not sure it will be cute for much longer though.
Here are the other words he is currently saying:
no, mama, dada, hi, bye, bubble, nana, papa, bupa (grandpa), mar ma (grandma), ball, baby, what's this, tickle, whee, wow, two, doggie, bat, bee.
He repeats lots of words, but these are the ones that he says on his own.
