With a gifted speaker comes some difficulty. Toodles, now 22 months, regularly uses 4 and 5 word sentences. The downside is that, when she asks for something, she doesn't understand concepts such as time or sanitation.
She may come to me while I'm handling raw chicken and ask for milk. Just a minute, please, I say to her. I want milk, Daddy. Just a minute, please. She begins to get frustrated and is soon crying and yelling at me.
This would be tolerable if it only happened, say, once a day. But it happens at least four or five times. Every day. At the dinner table. In the car. On a walk. At the playground. She wants something that isn't immediately available. And she gets pissed.
I have been trying to be patient, but I occasionally lose my mind and control and yell back. Of course, that only makes everyone upset. As with most undesirable behaviors, it is more a matter of time than teaching.
