"Big Questions from Little People" by Gemma Elwin Harris is a book for all those parents (and actually all have been in that situation) who have many times met with questions of their children that sounded so simple and easy to answer, and yet you didn't know or didn't know how to formulate the answer.
And, of course, for these children as well, to get deserved response nevertheless.
Some of these questions are classic ones like "Why is the sky blue?" or "Why is space so full of sparks?", some seem easy, although difficult to formulate short answer like "Why do have to go the bathroom?" or "Why are the grown-ups in charge?", while some are really tough ones to answer like "Why do wars happen?".
Gemma Elwin Harris has collected thousands of questions from preschool and school children in UK and afterwards sought help from hundreds from experts to answer them in simple language kids can understand.
Due to that, "Big Questions from Little People" is entertaining and fun book to read, full of small simple wisdom, book that you want kids to read which therefore can be recommended for your kids or as nice book gift for someone else's children.
So the next time you overhear that a child asked her/his parents one of these questions, you can offer help or just be happy that thanks to your child you've learned a lot of things that (only) seemed simple to answer...
