Lil D's Godfather got us one that has removable pages and it also came with extra pages to insert if needed. So I removed the Daddy page and put in an extra mommy page. I believe it is a halmark book.
MyOwnLittleStory.com is an online baby book that allows you to skip any pages that you want. Only the pages you choose to publish are included in the printed copy you order. They even have email reminders for every milestone....and, its a free service.
Re: Baby book that doesn't mention dad?
I bought this one at Target, they also have it on Amazon. I like it and its a flip book.

I found these online. I haven't ordered yet so I can't speak towards quality or anything, but at least they have the correct type of pages.
