The "after effect" of story book

Last 2 weeks, we borrowed a book from the library. In that particular book, there's two pictures - one with the baby wearing his own shoes ( the vocabulary that shows in that page is " Shoes" ), another picture with the baby wearing a bigger shoes ( should be his mummy's shoes ), compared to his own shoes ( the vocabulary that shows in that page is " Big" ).
So, after reading that particular book, Ee Shuen always tend to wear bigger shoes, like what she's doing in the photo!
