In Sweden, the image surprises no one.
"It's very important to see fathers walking in town with prams, it sets an example," explains Malmoe University sociologist Lars Plantin, who specialises in parenting issues.
Numerous sociological studies have shown that Swedish fathers are more involved in raising their children and domestic chores than fathers in other countries, Plantin noted.
They frequently drop off and pick up their children at school and accompany them to after-school activities. They take days off work to care for their sick kids, they put band-aids on scrapes and cook meals: Swedish fathers are now expected to share the tasks that once belonged solely to mothers.
In a sign of the times, a monthly magazine called "Pappa" has been published since 2011, targeting "the man who aims to invest time in his children, his relationships and his career."
Even at the highest levels of business and politics, fathers are involved in family life and the home.
Prime Minister Fredrik Reinfeldt has often spoken of his passion for hoovering and cleaning. While he and his ex-wife Filippa may now be divorced with three children, when they were married she was able to climb the ladder of her own political career while he ran the country's affairs.
Since 1976, couples who separate or divorce in Sweden are by default awarded joint custody, with many children spending one week with mum and one week with dad.
"The prevailing thinking is that the child does best when he or she has good relationships with both parents, which encourages the idea of joint custody," says Anna Singer, a professor of civil law at Uppsala University.
"The system encourages fathers to take their responsibilities, it has encouraged people," she adds.
Sweden's long tradition of gender equality naturally plays a role.
"Gender equality is a prerequisite for Sweden to progress. It's not a purely ideological issue, it's an economic one also," Plantin says.
Sweden "can't afford to have half its population excluded from the job market. It's not about leaving the men at home, but getting women to work more," he explains.
Official figures from Eurostat show that 77.2 percent of women in Sweden held down a job in 2011, the highest level in the European Union.
Children are guaranteed a spot in daycare as of the age of 12 months for a very modest sum, making it possible for women to return to work.
Yet Sweden still has a way to go in terms of equality in the workplace. While 82 percent of children have two working parents, only 42 percent of women work full-time compared to 74 percent of men, according to Statistics Sweden.
And when it comes to what is considered the symbol of gender equality, Sweden's generous 16-month parental leave that can be taken by either mothers or fathers, women still take the majority of it, claiming 75 percent.
When it was introduced in 1974, mothers took 99.5 percent of it. When one month was reserved for fathers in 1995 under a "use it or lose it" system, fathers slowly began staying home with their children.
In 2002, a second month was reserved for fathers, and they have no excuse not to take it: parental leave can be used anytime up until the child turns eight years old.
"We're heading in the right direction, but it's going too slowly," says Ulrika Haggstroem, analyst at the TCO white collar workers' union.
She thinks at least three months should be reserved for dads.
For Anders Weide in the park, spending time with his daughter was a "natural" choice. He has been home with her on paternity leave since January.
"I would have missed out on the relationship I have with Alma if I hadn't done it. We're closer as a family," he says. Employed in healthcare, he plans to go back to work in September.
While employers have to let both mothers and fathers take their parental leave, some workplaces are more understanding than others.
"My colleagues, especially the men, weren't very understanding," admits Set Moklint, 31, who works as an emergency call centre operator.
But he welcomes the extra economic incentive provided by the Social Insurance Agency: parents who share their parental leave both get a bonus throughout their leave.
"It gives us 120 euros ($155 ) extra each per month. We would have done it even without the bonus, but it helps," he says.
Fathers' involvement in the home also plays a part in Sweden's high birth rate, according to Lotta Persson, an analyst at Statistics Sweden.
In 2011, with 1.9 children per woman, the Scandinavian country came in just behind Ireland and France in Eurostat's statistics.
