As Gay Byrne used to say.



I'm afraid I have no idea. I imagine big books with plenty of pictures, fairy tales and stuff like the hungry caterpillar.



Beatrix Potter and Roald Dahl were stuff I loved to read at that age (Dahl wrote different books for different age groups, including adults) I remember reading Ladybird books when I was very young, which I seem to remember being about fairy tales (Puss in Boots, The Gingerbread Man, etc.) Avoid Chicken Licken (Chicken Little in the US). Scared the hell out of me as a child. My parents had to get the book out of the house as I couldn't sleep with it still in the house



Dahl wrote plenty of excellent stuff for older children also. Generally I suppose you move onto the kind of stories were children go off and have adventures on their own, without any adult supervision. So stuff like the The Famous Five, The Hardy Boys, etc



As a younger child Roald Dahl.



Apart from the fact that you should never trust a Fox as it will inevitably eat you, the main thing you learn is a love of reading and that is important for your overall ability to learn.



As probably already came across I did love Dahl. I also really loved Folk Lore and legends and would read those with delight as a child.
