What do babies actually see in the womb...

There have been a lot of theories about what babies see and feel in the womb, if anything, but has anyone ever thought to ask the children themselves?  When I was pregnant with Alex, naturally Charlie was very curious and wanted to try and understand what was going on in his own way.  I explained that his brother was very small and had to stay in my tummy until he was big enough and then I would go to the hospital and the doctors would take him out (fortunately he didn't ask too many questions about that bit!)

One night recently as I was settling Alex down to bed I could hear Charlie explaining all this to his Dad 

Charlie - When I was really really little I lived in Mummy's tummy
Daddy - That's right
Charlie - It was a bit scary though
Daddy - Was it?
Charlie - Yes because there were crabs, because Mummy ate crabs....and worms...and a BIG GIANT SHARK!

So there you go, one of the universes many mysteries solved and all we had to do was ask :)
