Hey,look how I feed my piggy!

One week ago,my hubby came back from his business trip. Like every time he comes back, he always has some coins. This time, Eveline saw the coins and said:"piggy,piggy!". I knew she wanted to feed her piggybank. I put her piggy one her little stool, in which there is a "hole" for her to put her hand in so that she can take it easily.
So, she was feeding her piggy with coins, but her piggy mouth is too small and it was a little difficult for her to feed it. Then, suddenly, she stopped and watched the "hole" of stool for a while and pointed it :"piggy!" . I realized that she found a "big piggy" for easier feeding. I said nothing ,just watching her. There is how she feeded her stool"piggy"
