Op you might get a better response if you titled the thread a bit more apt. Regardless from reading your post, you are a hell of a lot better off than most at the moment. Who knows what will happen in two years time, but on both of your joint salaries you should be well able to cope. I presume that the amount you have in savings is €40,000 which is not a whole lot, especially as your salaries are €130 k. For the purpose of discipline you might be best watching your spending habits and avoid the waste.
What is the point in panicking. You have purchased assets for your offspring. Start paying them off and remember no one ever said it was going to be easy.
