I feel like maybe this was a weird thing to read as a kid cos it seems more for grown ups, but I'll always remember The Little Prince as being one of my main childhood books.
My aunt died when I was 8 and a half, and I know it was one of her favourites. After she passed, my Mum and I used to read it together at bedtime.
...My other favourites were Famous Five - I wanted to be George so bad!!
When I was really small my dad read the Famous Five to me. This might be an exclusively British/Ireland thing (and really old there anyway) because Canadian friends had no idea what this is ("What, fat English kids who ate all day and solved mysteries? What?") but I rather loved them at five... After that, at six, Harry Potter took over for ten years. But I also loved Goodnight Mr Tom (who am I kidding? Still do) and Roald Dahl books, particularly Fantastic Mr Fox.
Also: The Secret Garden, A Little Princess, Tom's Midnight Garden, Charlotte's Web, The Sheep Pig, Daggy Dogfoot and other such things.
Before I could even really read I loved the Serendipity and Raggedy Ann & Andy books. Then when I could actually read by myself, I loved (in no certain order)
-Dear America and Royal Diaries books
-The Amazing Days of Abby Hayes
-Avalon: Web of Magic and Avalon:The Quest for Magic
-Series of Unfortunate Events
-Song of the Lioness quartet
-Harry Potter :)
As a kid, I didn't branch out much in my reading. I stuck to authors/series that I knew and loved. I'm pretty sure I read every single Boxcar Children and Magic Tree House book. The Phantom Tollbooth, by Norton Juster was (and still is) one of my favorites. I was a big fan of the Redwall series, by Brian Jacques, The Dark is Rising series, by Susan Cooper and a couple classics: A Little Princess and The Secret Garden.
Oh and of course, Harry Potter :)
I didnt really start rreading untill I was around ten-ish. I had a bit of a learning dissability that just made it way to hard for me to consintrate for that long. Lucky for me I had an amazing older sister that would read to me( she actualy read the first Harry Potter alowed to me). I LOVED the Mrs. Pigglwiggle books. I also had a 3rd grade teacher that read us The Sideways stories from Way Side School. When I finaly started to read on my own I liked Mr. Poppers Penguins, The Magic Tree House and 100 Dresses. But my all time favorie then (and still now) is Ella Enchanted.
When I was six my brother read the first HP book aloud to me ^_^ It's actually what got me into reading in the first place (I like to say he created a monster :P)
Older siblings -- fab, right? :D
