Llama Llama books are a fan favorite of my niece.

My kids love:
Maurice Sendak (especially In the Night Kitchen!)
Julie Donaldson (The Gruffalo)
Pete the Cat books
Little Mouse, The Red Ripe Strawberry and the Big, Hungry Bear - by Don and Audrey Wood
Ian Falconer (Olivia books)
Sandra Boyton
Mem Fox

ETA: The Llama Llama books are big in my house too!

My LO loves all kinds of books. On one hand she's been getting more into "stories" but then she's also still loving simple things like lift the flap books.

One other unique kind she already likes is those "find and seek" books.
