There is some good anatomy of the foreskin and intact care information at Circumcision Decision-Maker website as well as the pamphlet "Foreskin Care: A Parent's Guide" you can download, email, or print.
Intact Care pamphlet
Woah, the baby on the cover of that e-book is totally creepy looking. For a moment, I was thinking that I was a bad mother. My children are growing up. I never advised my son on proper care. Now, perusing the forums I suspected I might catch up. But, I can't download that book. Thank you for trying to educate people though.
