Calvin's First Spontaneous Phone Question

This morning I called home as usual to say "good morning" to my family. Luiza and I were talking about how difficult Calvin has been with his fussing lately. Whenever he does not get his way, he makes a growly voice that shows us that he's angry, or he will yell "The monster!" at us or his brother. It's become quite tiresome, so we have really been addressing each incident and do not want him to get away with it any longer. Even when he's happy or playing, he seems to be grumpy.
So, on top of watching his diet (which we had started loosening up on), we are making sure to ask him to stop fussing and letting him know that he is hurting our feelings when he does this. Luiza spent a whole half hour with him in the bathroom (to limit any outside stimulation or distraction), working with him to realize that he can't fuss like that.
By the time I called home, Calvin was now in a much better mood. I asked to say hi to him on the phone. Normally, he follows my lead and answers my yes or no questions. Then he'll tell me something about Thomas or something watching TV. He rarely goes "off script" in our dialogue, just preferring to stick with the good old statements that he knows.
But today, the first thing I hear is a spontaneous, "Hi, Dada, is Ben coming over to play today?" Wow!! That blew my socks off! I said yes, and he said he wants to play trains with Ben. Haha. It is amazing what a little thing like this does to encourage us. It might seem small to most parents, but this was a real-life conversation happening here!! Praise God for His faithfulness to us!!
