Um, no. The medium-term child costs are set way too low. My brother works as a financial advisor in the real estate sector and has taken the trouble to calculate the actual child costs for his upper middle-class standard of living. He always has the numbers handy when clients want to finance houses. He has three children between 9 and 17 and came to 800 euros per month per child for last year. Food, insurance, sports, music lessons, clothing, Christmas and birthday presents, children's birthday parties, sports equipment, school activities, courses, hairdresser, braces, tutoring, learning materials, pocket money,... sure, ski trips and class trips were canceled, but more tablets and gaming devices etc. were needed instead. If your wife then has a third child, she will certainly no longer work full-time. Or you will need a cleaner. Most women reduce their working hours a second time for childcare during school age or to care for parents. On average, a child costs 148,000 euros until their 18th birthday. Conservatively calculated. In [Münchenundumzu] rather more. School time often requires more supervision than daycare time. And not to mention special support or personal sacrifices.
