Born with Sin?

I've heard it said that we are born sinners - full of sin.  But this so contradicts my experience with my children. One of the most spiritual experiences of my life has been looking into the eyes of my newborn children.  I really can't explain it - but it felt like their eyes were truly windows into the infinite - as if I was looking in the eyes of some creature fresh from heaven - as if I could still see the reflection of God therein.  I spent many many hours just holding and looking at Clark- getting lost in his eyes (I didn't have as much luxury of time with Juno - but I also did some staring into the infinite of her newborn eyes too).

I did some internet research on this in the past - but was relying on others finding passages for and against the notion that children are born sinners - as opposed to being born destined to become sinners.  Now, I want to record here any passages I see that weigh in on this --    

The first is: 

 Genesis 8:21
"The Lord smelled the pleasing aroma and said in his heart: 'Never again will I curse the ground because of humans, even though every inclination of the human heart is evil from childhood.  And never again will I destroy all living creatures, as I have done."

I note that God says every inclination of the human heart is evil - from childhood.  I think this means after childhood - but I have to admit it ambiguous as to whether this could include childhood.  But it clearly does not say from birth.  I would think that if God wanted to say we are sinners from birth he would have said that - as it would be a more powerful statement.  But instead it is from childhood.
