This doesn't make you unique... and it certainly won't make the other drivers better and more cautious - sorry, just cautious - than if you did not have a baby on board. Seriously, what is up with that?
I suspect strongly that this is a form a bragging.
I hate to disappoint anyone with my normally cynical attitude about the procreational process. And I am not saying that your kids aren't special and that they aren't great. But bragging that you had a kid? Again, not something unique. More people have them than don't and I'm sorry, but anyone can do this - for the most part. In fact, I'm surprised at how many people just, oops, get pregnant and then decide, why not, I guess I'll have it.
What kind of attitude is THAT about a huge, life-altering decision that you have to live with for the rest of your life?! I can't believe that. What a stupid thing that is. It is one thing to plan for this but I have found throughout my life that most kids are not planned, they are mistakes.
That is a helluva mistake.
