My 19 year old daughter needs to make a list of all the books she loved as a child. I can’t remember the name of her first favourite. It was a board book, purple or blue and ended with a mirror and the last line ended with “you” (as in the baby in the mirror). It rhymed and may have been twinkle twinkle little star but when I google it looks different. I think it was part of the patacake range but can’t be sure. Hope someone can help.
