This was a category that had many wonderful entrants – children’s books can be special for so may reasons; the illustrations, the prose, the language, the characters, for how many times your grandson asks you to read again 🙂

Reading, Writing and Riesling 
I’m so glad you included this category, Carol. I think it’s easy to forget how important reading with/to children is. It has so many benefits for all involved, and it’s made even better when the book is engaging and appealing. People think it’s easy to create a good children’s book, but it’s challenging. Kudos to those who do it well.
Thanks Margot – I think we are so lucky with the quality of children’s books today.
