Know a dad-to-be who is clueless about the whole pregnancy thing? Send him a link to Dad's Pregnancy Guide on one of our favorite Daddy blogs, hisboyscanswim.com. There he can see, week-by-week, how big his in utero baby is, in dude-friendly comparisons. ("Week 16: Man, you are a STUD! Your baby is now the size of a small stud finder.") Sure, there are probably men who would be insulted to be stereotyped as someone who only thinks in terms of footballs, cars, and breasts, and there are probably women who would find this guide just as useful, but I'm sending this to the dads I know, anyway.
