While I agree with that shrink part, you must be living in a bubble for the family part.

Literally all my colleagues in past 5 jobs (that few hundreds guys) have kids if they are over say 35. All colleagues of my wife. All of our friends. I cover western (Switzerland) and eastern Europe here. Same for Swiss colleagues and foreigners. Folks with nannies or family close but also raising their kids just by themselves, like us.

2 kids are standard, 3 are actually slowly becoming a norm. 1 is rare and more related to medical issues rather than an actual decision. From my own personal experience being raised as a single child, it sucks in many ways and will affect you negatively for rest of your life, regardless of all the love you received from parents (which of course helps but doesnt mitigate this).
