My daughter was 2.5 years old when I started to tell impromptu stories before naps and sleeps. That was almost 2 years ago. She loves it so much that her excitement always push me to persevere. Always 4 before nap and 4 before sleep. Very often I felt bad that I did not jot down the interesting ones. I was surprised I could do it. And most importantly all these stories stimulate my girl to be very imaginative. Sometimes she will decide on the type of stories and sometimes she will suggest how it should go and end. At four years old, she makes her own stories, creates her own games and loves many other open ended toys.
