With DD, I don't think I picked up a baby book for a while. It may not have been until after she was born? I can't recall.
I have loads of u/s pictures and things that I want to start putting together, so I was thinking of getting DS a baby book sooner then later. DD has Baby's Record Book which I like but I sort of want something different.
I loved DS2's baby book b/c it was a binder as well. You could add your own pages and pictures. Just hole punch and voila! I *just* bought #3 a book today. It's not as great as DS2, but it will do. It seems to be tricky to find a unisex book. :-/ Oh well. I'll have to look for DS2 book and get the brand for you. It's really a great one.
