A young boy records the ups and downs of life as a new big brother in a scrapbook of funny, earnest letters and other touching memorabilia.

There's a baby on the way! Of course, Mike is very excited and curious about his new sibling. And he's very eager to assume his new role as a big brother. To start, he's decided to record his observations and experiences in a series of letters to the baby, displayed here along with playful illustrations of Mike's own drawings, family "snapshots," and even a sonogram. Whether Mike is feeling like an "invisible boy" or boasting of his new sister's talents, whether furious when she breaks his favorite toy or proud to save her from a hot curling iron, his account of his first year of life as an older brother evolves into a very special keepsake — and a funny, honest, and heartfelt tribute to sibling relationships.
