Every nursery and reception class should have a copy of Wake Up Ginger by Ant Parker, a Flip the Flap title from Red Fox (pound;3.99).
Most of the book consists of the repeated refrain “Here I am GingerI” “You can’t catch me!”, so that even non-readers will quickly be able to find the words (in various positions on the page) and begin to develop speech-print correspondence. The framing sentences have just enough variation to hold the interest of those who are already reading.
