A lot of countries have baby bonuses. This particular example is notable for how Soviet it is.
I support incentives for childbearing, but that part jumped out at me too. The mark of 10 children is probably not a coincidence considering that Putin has been actively invoking Russian memory in other aspects.
My personal favorite childbearing incentive in the world is that in the country of Georgia third-born and later children are personally baptized by the Catholicos-Patriarch. I wonder if parents feel somewhat cheated since he is old and decrepit now and needs an assistant to actually dunk the child. Maybe not though, since he is overwhelmingly popular in the country.
