I counted one legit laugh in the Danish pregnancy comedy “Maybe Baby (Bytte bytte baby),” a film about two couples of differing ages experiencing the (scientific) miracle of childbirth.

They have a joint baby shower, and the holisitic “hippy” couple’s mom brings just what you’d expect — a cake shaped like a vagina. Vagina cakes always crack me up.

This blandly predictable difficult pregnancies comedy’s one wrinkle is having the pricey, busy and carely private in vitro clinic that hard-driving, demanding lawyer Cecile (Mille Dinesen, fierce and kind of funny) and her husband Andreas (Lars Ranthe) visit as a last resort mix up her fertilized egg with that of younger, closer-to-broke Liv (Katinka Lærke Petersen) and partner Malte (Kasper Dalsgaard).

As the fertility specialist (Thomas Bo Larsen of “Another Round”) is prone to implanting eggs and telling the biological father “We finished without you. I’m almost like a stepdad!” we can see how that might happen.

Fine. Fine. Just bring your babies to term and swap them, right?

But short tempered Cecile is ready with a writ, actually a contract, to make sure that happens. And laid-back Liebraumilch drinking Liv — Ms. “A Little Wine Can’t Hurt” — isn’t sure about that, as she expends to bond with this child growing inside her,

Cecile? “I refuse to have their hippie baby!” (in Danish with English subtitles).

Each must bend to the other’s preferred way of approaching pregnancy to mimic the experience the child will be brought up in.

Dinesen (“Hold My Hand”) is the only one who reaches for laughs here, although Larsen sneaks in a lighter touch. Everybody else plays this fairly straight, and dull.

Nothing particularly original or hilarious spins out of this Pia Konstantin Berg screenplay. Cecile’s sexist “I would have like to have gotten a head’s up” boss is predictably unsupportive.

But as the mothers fight over holistic, laid back, “no meat,” herbal this and “natural” that vs. Cecile’s “no cats — litterbox germs…No wine!” and “My baby needs MEAT,” the film lapses into that just-as-sexist menfolk are the reasonable ones ytp[, with Andreas consoling Cecile, accomodating Liv and Malte and Malte protesting how Liv is leaving him out of the decision-making process.

Even in enlightened Scandinavia, old movie comedy tropes die hard.
