Since the first "Hangover" movie, I've definitely seen an uptick in movie posters featuring Baby Bjorns (or the generic equivalent).
The latest example is "Neighbors," a film about a new dad (Seth Rogen) finding himself living next to a frat house.
Visually, a baby carrier does more than show that a character is a dad. The infant literally becomes a burden to bear — symbolism! Plus, let's face it: It makes a man look ridiculous (and the Baby Bjorn is the most ridiculous-looking of all baby carriers).
Some posters also riff off the incongruity of otherwise cool-looking dads with babies strapped to their chests. Here's the poster for the show "Guys with Kids" (see, they're wearing sunglasses!)...
..."What to Expect When You're Expecting"...
...and who could forget this one? (As much as you may have tried.)
Of course, the ultimate befuddled-dad movie was "Three Men and a Baby" in 1987. No baby carrier in sight.
Believe or not, Baby Bjorns did exist back then — they were first made in 1973 — but they hadn't yet become a pop-culture phenomenon. I'm sure if they ever remake this movie (and they will), the poster will feature baby carriers aplenty.
In real life, I see relatively few dads using Baby Bjorns. (I'd say backpack-style carriers are more popular.) I've always been a fan, though.
I guess I don't mind being a movie cliche.
