@bruin My family is formed through adoption. I bought that book when we adopted my son was born and I gotta say, I wouldn’t count on that book being what you’re looking for.
I did Qeepsake where they send you questions over text and you answer them with words and photos. You can also add stuff you want to include without a prompt. Periodically you have the texts and pictures bound into a book.
Many of the questions are about development and firsts, so traditional, probably similar to your other kids books.
Some of the questions were just not appropriate to adoption but I would just text “skip” so they don’t appear in the book at all.
I also wrote things in like his birth story, the very basic/happy parts. For me, I focused that on just the happy things that he might one day casually share like I’ve done with my own baby book.
The tougher/more personal stuff is in a separate google document. For my son that is some of his adoption info and also medical things that I want him to know but not have to look at if he wants the fun/cutesy type thing most other kids have.
My son’s godmother takes a whole different approach and makes a calendar with firsts listed plus photos or a small paragraph about the big events for that month. I’m not organized enough for that - she’s great at scrapbooking.
