Has anyone ever really wanted to have children and then suddenly started questioning themselves?

I'm talking about people who had very close and kind relationships with their mother and who like children, not people who hate children and hate the idea of ​​family.

Does anyone here know that they would be a good mother but at the same time have perhaps decided they don't want to be for other reasons, such as wanting to have a passionate marriage without children interrupting, wanting to be able to sleep in late, wanting to continue having free time for hobbies and everything else?
