Here's a little incident that just reinforces the fact that children are sponges. Yesterday Amy was talking to Isaiah about something (I don't remember exactly what) and when he replied, he said the correct answer and added "blah, blah, blah" at the end.
Of course, I knew he had to hear it from his mother because when she's talking on the phone and doesn't want to try to repeat something verbatim, she substitutes "blah, blah, blah" instead. I guess he's heard it enough that he thought he could say it.
That serves her right. Blah, Blah, Blah
