We have three girls, ages 14, 12 and 8. We need book ideas for a 3 year old boy. I got some Thomas the Tank Engine and Curious George but didn't know if anyone out there had a toddler boy who LOVED a specific theme or character??? Wanna share your experiences??

THANKS!

I second the Eric Carle books!  Also, there's a series of lift-the-flap books that my sons loved at 3 and 4 called "Where's Spot?"  (Spot is a dog.) 

Here are some my son loved at that age (ones we read more times than I can count):

Little Critter's Where's Kitty by Mercer Mayer. It is a lift a flap board book and you look all over the farm for Kitty.

Pat the Bunny

Goodnight Moon by Margaret Wise Brown

The Very Busy Spider by Eric Carle

The Poky Little Puppy

Caps for Sale by Esphyr Slobodkina

My daughters and my grandsons have all enjoyed the Mercer Meyer critter books.  I think they are great for small toddlers and also beginning readers.  We have always had fun looking on each page for the spider and grasshopper friends.

The Henry and Mudge series of books by Cynthia Rylant are great.

My sons loved  Mike Mulligan and his steam shovel.

Other favorites were:

The monster at the end of the Book

How do Dinosaurs say goodnight

Caps for Sale

Hop on Pop

Old Bear

Anything by Dr. Suess is great because of all the rhyming. 

I second Eric Carle....my boys loved The Very Hungry Catepillar

The Bernstein Bears is good too.  Some of them are simpler and are good for a young age and then there are some that are good for older ages like 6 +

My nephew is at that age right now, he loves Thomas the Tank Engine (of course), anything with Elmo on the cover (although he has taken to There's a Monster at the End of this Book), anything revolving around Disney's Cars, and (as I have recently discovered) anything that has a vehicle with eyes that talks (apparently that is cool to a 3 year old, even if it is not Thomas).

Dr. Seuss

Little Critter

Blues Clues books

The Grouchy Ladybug

Look and Find books

Those are my 3 year old sons faves. :)

I have two sons, one just turned 5 & the other will be 3 in a month...here are some they like(d)...

If You Give A Mouse A Cookie by Laura Numeroff ( really any of her If You Give a _a_  books are good)

I definitely second the Eric Carle books & Mercer Mayer Little Critter books.

My Car by Byron Barton (and some of his others)

Llama, Llama Mad at Mama & Llama, Llama Red Pajama by Anna Dewdney

Curious George books

The easier I Spy books or others like them

books by Todd Parr

Mercer Mayer is always a hit, also the Spot books (Spot Goes to the Farm, etc)  And the small I Spy board books.

My 2 year old son is into Arthur books by Marc Brown right now.  He can't get enough.  Also Danny and the Dinosaur by Syd Hoff and the Little Bear books by Else Holmelund Minarik.  All of those are readers, but as long as the attention span is there I don't think it matters.

As far as more picture books, Denise Flemming has some good ones.  Barnyard Banter and Beetle Bop are two that my son loves.
