I've got a first kid born lately and never crossed border with her yet

I am a Finnish citizen, my wife is Russian, kid has double Finnish-Russian citizenship (and passport and properly translated and apostilled birth certificate). We are likely to travel rather often between Russia and Finland, sometimes together, sometimes just my wife and a kid.
On the Russian side I checked that having just a birth certificate and one parent is enough to cross the border.
Do you know what's the situation on the Finnish side? Is just a birth certificate + one parent enough to cross the border? Or maybe you need some sort of permission from the other one as well?
