Re: Making a board book with your own pictures?
Not sure if you have time, but can you make your own with pictures with some captions. I have so many big sister books...take lines from those books with pictures of your son.
I want to make an Alphabet book for my girls and my nephew... pictures for each letter. So Snapfish make board books or are they the thin pages like a photo album?
Not sure if this would interest you, but you can buy blank board books and illustrate them yourself:

Pretty cool idea, and one that your DS can get involved in too. Just a thought.
