Did Adam and Eve have children in paradise? I was just reading the account of Adam and Eve in the NIV 84 and it doesn't really say they didn't.

The Bible does mention when Sarah had her first boy. When Mary had her first son. But not really when Eve had her first son. Does it?

I'm just wondering because I have in my mind that they had children after they got kicked out. Partly because of the common belief. What am I missing?
The crux of this question is really How long was it before Adam and Eve sinned?

The biblical record only has the following facts:


Adam and Eve's first child was Cain, and the second Abel, by virtue of Genesis 4.
Genesis 4 also suggests that Seth was not born until after Cain killed Abel, an act that could not have occurred in the Garden.  
Genesis 5 says that Adam was 130 when Seth was born, so that establishes an upper limit for the length of the time on the garden.  (I will repeat my assertion that had I been Eve, I only would have lasted about 32 minutes before getting kicked out, nonetheless I digress.)


This means that the only two children who could have been born in the Garden are Cain and Abel.

Circumstantially, I would have to suggest that the evidence would make a much stronger case for the children being born after rather than before:


There is no mention of anyone other than Adam or Eve being cast out.  (And the Lillith thing is just Jewish legend.)
The fact that the narrative records the conception of Cain after Genesis 3 gives no reason to suspect it happened before.
