There is a confusing but splendid program called elterngeld-plus. You take half time (25-30 std/wo) and get half money but for twice as long. If both partners take it at the same time for 4 parallel months then you receive a bonus 4 months (which you can also take as half time which means 8 months). You could theoretically get 28 months of half-money/half-time.
