Over the summer I was browsing
Barnes and Noble for some fireman/firetruck books for Luke when I came across this one on the bargain shelf (LOVE that shelf!).

So, for all of the obvious reasons (we wanted to introduce Luke to the idea of being a big brother, the baby in the story was gender-neutral and we didn't then know the sex of the baby, etc.), this was a great book. So, I was sold on it before I even really opened it to read it ... but once I did I was certain that Luke had to have it ... the big brother's name in the story is Luke!
Almost as if on cue just a few weeks before his new sister arrives, Luke has decided that this book, which he previously had little interest in, is his absolute favorite. We read it several times a day and the pages are suddenly starting to look worn ... and, in my opinion, there is nothing better than a book that is well worn and loved!
