I understand what parent is saying and this Freiburg example is a good one: there are going to be situations and times (such as the birth of a newborn) where following strictly to the rules (you have a limited amount of trash to dispose) just isn't viable or even possible. Anything that deviates from the norm and established rules, even slightly, is at least frowned upon and at most results in a fine or some other material punishment in Switzerland (I can't speak to Germany).
No you are wrong. People living there have had children or have children. Everybody knows when making an exception is ok or not, or when the allocated trash associated to a household must be increase.
The assumption that people living there are intolerant of babies and families is false.
On top of that there wasn't, and for Geneva isn't, any allocation of trash or similar stupidity. When I was moving out of Lausanne, they introduced special garbage bags that were supposed to be used (for our bin it was 2chf per piece), to pay for recycling. Avoiding those would be fined if found out.
But if I threw out 200 of them per month, that would be my own thing. Nobody frowns, complains, cares or anything. People just go about their lives in pretty sensible ways.
In Geneva, I can throw trash in Migros plastic bags if I want, nobody cares. No clue about current Zurich, 10 years ago I didn't pay anything neither.
That's a ridiculous system. "Everybody knows when it's ok to have more baby diapers in the trash" as a temporary hallway pass is a symptom of a failed mindset.
