Seeking attention?

This gal complained about a pain in her right foot on Sunday. She said,"My feet very painful"and "I don't know walk" for the whole afternoon. We checked her right foot but could neither find any bruises nor any signs of swelling. After her nap, she complained about the pain again. She refused to walk and mummy and gor gor carried her from place to place at home. She would resort to kneeling down like this and move around the house on her knees.

I was worried and thought of taking child care leave to bring her to the doctor for X-ray on Monday. Later in the afternoon, we brought her along to Clarence's Skating Halloween Party and I told her to sit on the mat and rest. After we arrived at the park shortly, she was up and running all round. She could even jump and climb and hang herself like a monkey on the bar. Her right feet miraculously recovered.
However, after we reached home and showered her, she complained about the pain again and knelt on the floor to get me to carry her to bed.
When I went to her childcare yesterday, I spoke to one of the teacher and realised Vincy did the same thing in school twice a week ago. Is she trying to seek attention? Asking people to carry her around or is there really something wrong with her foot?
