Baba Yaga the Flying Witch is in Usborne First Reading series, written especially for children who are learning to read. With delightful illustrations, these books combine great stories with simple text to excite and inspire any beginner reader.
If you haven't already, you should make read along books part of your child's regular reading routine. Not only will read-aloud books introduce your child to new words and how they are pronounced, but they will bring the words to life for your child in a way that silent reading doesn't. Read alouds can also give new readers a break from working so hard and make books fun, which can build a lifelong love of reading. Research has shown that children who enjoy reading and spend more time reading for pleasure have better reading and writing skills, a broader vocabulary, and even an increased general knowledge and understanding of other cultures.
Remember every time you share a book with your child, you are doing something really valuable - helping them to discover the pleasure of reading.
