Last week we played and played with it. I'd roll it to her, she'd reach out and corral it and bring it in and then beat on it like a drum to celebrate the successful transaction.
Last night, The Wife and I broke out the ball again, and the reaction was much different -- shrieking and crying. She acted like she was afraid of it. Same today -- I produced it and NJ immediately whined. When I rolled it to her, she leaned over and grabbed it, pulled it close and beat on it again. Crying the whole time. I rolled it one more time, and the crying intensified. She caught it, and when I went to retrieve it she was actually trembling. So: Ball play is over.
