Miller is now crawling and has discovered that she can use her hand to bat a soft rubber ball across the floor. For the last two weeks, Miller has spent much of her crawling time batting and chasing her ball around the room. Today the ball rolled under a table that was pushed up against the wall. Miller tried to crawl under the table but was blocked by two chairs. Miller then crawled to the side of the table and stretched out her arm to try and reach the ball. When this was not successful, Miller crawled to the other side of the table. This time she lay face down and wriggled under a chair. She managed to bat the ball from under the table but then Miller appeared to be stuck under the chair. At this point Miller squealed and looked to the educator but did not appear to be distressed. I responded by asking if she was stuck and I then helped her by moving the chair. Miller smiled and then crawled off in search of the ball.
What does this observation tell you about Miller's physical, problem-solving and communication skills?
