Motherhood

I have always wanted to have children.
And I sometimes wonder... why?

Where does this sudden, unprecedented feeling come from? Why do I suddenly tear up or feel (almost humiliatingly) emotional around children?

Maybe, as women say, it's "my internal clock ticking".
And yet, I feel like this answer is way too simple to be warranted any attention. After all, I have numerous female friends who, at my age, have no intention whatsoever to have children or who even think about children.
So what am I suffering from? (Okay, "suffering" may be too strong a term, but indulge me please).

I remember being shocked once when a friend told me that wanting to be a parent was a unique egotistical trait. In other words, one wants to have children because one wants to reproduce "oneself". To have a child is to copy yourself in some way.

Yet I disagree. However, I do admit that children, no matter how much they hate to do so, become their parents. That said, once children become adults, they somehow learn to develop their own interests, to lead their own lives and to love their own people.

So why do I have this need?
I'm just asking. I wish I had the answer.
