But don't overcorrect. Many people are ready for kids earlier than they think.
From my dad, "it's a lot more fun raising teenagers in your 40s than in your 60s".
No one is ever ready for kids. Wait until your spouse or partner agrees that they want kids, and go for it.
That's right, but I'm sure you agree that there are different levels of "not ready". I was thinking of writing "have kids when you no longer think it completely out of the question", but that's a bit complicated.
