I worked at ALA Midwinter as a volunteer, so got to explore the exhibits for awhile after. I spent most of the time looking at new books. Here are some of my favorites (thanks to Betsy for ordering quickly):
Martha Doesn't Say Sorry by Samantha Berger
Little Oink by Amy Krouse Rosenthal
Stella Unleashed by Linda Ashman (Colorado Author)
Also since Beth Krommes won the Caldecott, we have ordered more of her books. My favorite is Grandmother Winter.
You can always find more new books, dvds and cds for kids on Tales' Treehouse. I update it a couple of times a week.
