Government workers in Sweden get 13 months paid maternity leave. That's a pretty good incentive. But they rank 187th in the world by birth rate, according to the CIA World Factbook.

How does that make it less of an incentive, though? It's better than no paternal leave.
In the end, though, people usually don't get children on a purely economically rational basis. Sweden also has daycare prices that scale with income, free and relatively high quality public and private schools, child benefits and free dental and healthcare for children.
