Here are some my kids like...
(I'll post some specifically Catholic ones in the other thread some other time.)
Caps for Sale by Esphyr Slobodkina
Sam and the Firefly and
Are You My Mother? by PD Eastman
The Seven Silly Eaters by Mary Ann Hoberman
I'm not a huge Margaret Wise Brown fan, but I read somewhere that
Goodnight Moon contains every sound in the English language, so I read it regularly to my kids who seem to have developed their own language due to the number of words they routinely pronounce incorrectly. : )
Especially if your toddler hasn't mastered the basic colors yet,
Brown Bear, Brown Bear, What Do You See? by Bill Martin is a good read and easy for little ones to memorize and "read" themselves.
For the early talkers (well, pretty much everyone likes this book), there's
Mr. Brown Can Moo, Can You? by Dr. Seuss. We have the board book, but I think there are more noises to immitate in the full version. (While Matthew is a big Dr. Seuss fan, I really only like the ones that actually make sense. Call me picky, but I don't like to explain at about age 3 that you won't be finding any Wosets in our closets and we can't get a Zans to open our cans. And, yes, Dominic has asked repeatedly if we could buy one of those Cat in the Hat cars to clean up his messes.)
We just added
Harold and the Purple Crayon by Crockett Johnson to our collection. I'm hoping it'll inspire my kids to be a little more creative in their drawings. ; )
The Little Engine that Could by Watty Piper
Eric Carle has several good books for toddlers. We have
The Very Hungry Caterpillar and
The Very Busy SpiderThe Bear that Heard Crying by Helen Kinsey is based on a true story. We checked it out at the library and enjoyed it very much.
