New reader book suggestions?

I'm posting this multiple places in hopes of getting multiple recommendations:)

My son, Gman, is just learning to read. He's able to sound out 3 letter words and is working at school (and at home) to read more complex things. He gets frustrated at home and tries to go too fast. I don't push him to read when he doesn't want to, but I do encourage it as I love to read and I think it's great hobby. He has worked his way through the first set of Bob Books by Bobby Lynn Maslen and is starting the second set. Does anyone have any recommendations for books that he might enjoy that are not too difficult?

He may enjoy the Dear Dragon books by Margaret Hillert, or any of her others books.

Here's a cute one, I Can't, Said the Ant by Polly Cameron. Short words that rhyme, and a droll story line.

I love love LOVE that book, Sunniva! It is cute, and clever, and the best read-aloud book...the kids (Kindergarten and 1st graders especially) love trying to guess the rhyming word on every line.
