It gets difficult - again, from what I've seen - when you run into edge cases that brush up against how things are traditionally done. I don't think that a lot of companies have gotten a handle on how to accommodate women with children. For example, average working hours can easily go past 17:30, but most kinderkrippe close at 18:00. There are also social expectations that are hard to interpret or otherwise navigate, especially if you're not a native citizen and didn't grow up in the culture.
I think that the situation isn't that different from a lot of other European countries, and it also appears to be improving (even in my limited time here, I've noticed that there has been a lot of discussion around the gender pay gap, and a stronger focus on accommodating women with children at work).
