Hello-this is a Wonder Book, #818 titled "Merry Christmas Mr. Snowman!" Really cute story; I found a used copy sometime in the 1980's. Originally published in 195l, and called "The Snowman's Christmas Present", #572. Story does have two brothers and a sister, Billy, Mary and little Davey (the one that says "Me, too!") You can probably track down a copy online through Amazon, ebay, or numerous other used-book sites. Happy Hunting!
There was a book I remember as a child that I think was a Christmas book. The kids are getting ready and excited for Christmas. They are two brothers and a sister outside building a snowman. One of them says, "Me, too!" said little Billy. "Me, too!" or something like that.
Anyone remeber this book!?!?!?
