When people show you their baby pictures and you find yourself having difficulty exhibiting the required amount of cooing, do what I do: When you see a baby, don't see a baby. Instead see....Puppies? Or....Kittens! Or whatever else that makes you coo. If need be, you could see a baby with a cigar in its mouth. That might make you coo, or at least smile, which can sometimes be construed as cooing. In which case, you're home free.
