TBH at 3 I think you're better off with things like Hairy McClary, Who Sank the Boat and so on. At that age they love the repetition and being able to 'read' a book when they have learnt all the words.
Yes - didn't realise you said 3. Get a base of fabulous picture books - Mem Fox has alot of great ones, the Lynley Dodd ones definitely.
