If you gave up work, your husbands take-home would go up €4530 this year, all things being equal. You would probably have a net monthly fall in income of circa €2k. Saving €500 on after school care would bring the net monthly difference to €1.5k. If you had the possibility to get rid of a second car and save on other work related expenses (lunch, clothes?), and made a few lifestyle changes it may be more doable than you think. Personally, I wouldn't pay money into a pension unless such money would otherwise be taxed at the higher rate.
