Photo book help

I was planning on making a Shutterfly book for my daughters first year. I started working on it and found out that the page limit is 110 pages. I used 40 pages for her first week of life! So there is no way I'm going to be able to fit a whole year in one book.

How do you split it up between multiple books? Do a monthly book? Every 3 months? 6 months? It's going to bother my OCD not to have one actual book, but I can't narrow down my pictures any more than I already have. (Yes, I'm photo obsessed).
