Following Judith Rich Harris, author of "The Nurture Assumption", I doubt that birth order has an important effect on parenting style or other aspects of personality once someone leaves home:

Why Do People Believe that Birth Order Has
Important Effects on Personality?

by Judith Rich Harris

In the first two essays on this website, I summarized the results of more than half a century of research on birth order. My conclusion was that birth order does not have noticeable effects on adult personality. The question I must deal with now is: Why do most people -- including most psychologists -- continue to believe that birth order does have important effects on adult personality?

In this essay I will discuss several sources of the belief in birth order, including people's subjective impressions based on their own personal experiences, flawed or misleading research, the tendency for research to be published and publicized only if it supports the belief in birth order, the impressions psychotherapists get from listening to their patients, and biological factors.

It isn't enough, however, to explain why people came to hold a particular belief. I also have to explain why they cling to it so tenaciously in the face of disconfirming evidence.
