Big Sis is 9 and LOVES these books. She is definitely one to ask questions and half the time I have no idea what the answers are. These books give her those answers and hundreds more answers for questions she hasn’t even asked yet. Once in a while she will spew a fact at me and I will ask her how she knew that. She usually responds that she read it in a book. That makes me one proud Mama!
