I think tightening the belt with children is more due to reduced income when one partner or both reduce their working hours. 2000€ net gives about 1300€ parental allowance, or rather a bit less, stretched over 24 months... 650€ per month instead of 2000€ salary, to stick with the OP's numbers. That's roughly 1350€ missing every month. That really hurts here. And if a second child comes along, with parental allowance then calculated at best based on part-time work... it gets even tighter. One year of parental leave and then working at least 50% would be more feasible financially. But many families don’t want that. In this case, one can only advise keeping a reserve to "bridge" these periods. Better to take out a little more credit now.
