I noticed when visiting the US that breastfeeding was not very normal. Like they don't even teach it in a standard hospital.
Finnish moms are getting longer maternity leave than most countries in the world with this system. If other countries can manage with their short maternity leaves, I am sure Finnish mothers can manage too.
I mean I agree with you in principle that moms are needed for longer time than dads, but too often such questions are raised in an a disingenuous fashion to push back against gender equality.
What we do in Norway is that moms get some extra time at work for things like pumping. I believe the first year you get something like 1-2 hours at work for breast feeding.
As a dad I was feeding my child milk which had been pumped earlier.
