I have created three, and I have to say that "A"arron's is by far the best... probably because it looks like a baby book. It covers the first year of his life, his milestones through his adoption date. For "C"indy and "B"ella I am missing all of their milestones and baby pictures. I do have pictures of their birth families from physical photos given to them while they were in foster care... but the books still seem incomplete.
There are websites that you can order Life Books from and even suggestions on what to do (personally, I prefer Shutterfly hard cover books -- sometimes there are Groupons for them for only $10 plus shipping -- I have a fear that pictures/pages can get removed from a binder and then the child has nothing).
