Baby album - 11 months

I'm making a first year+ baby book for my Aunt's first baby - the plan is to have a one page LO for each month Sept 2011 (birth) - Dec 2012, with a divided page between each where she can put extra pictures for that month...I'm planning on slipping 11"x 12" "milestone" pages as hidden pages behind the month pages so she can put those behind the right months later as they happen.

I'm making the book uniform by using a kraft cardstock as the base for each page, using grey cardstock to mat the photos, using the same line of journaling stamps, and using the same month tags and calendar circles on each page. TFL!!
