This may be the proof for those who do not think babies can learn from the womb.
I have come across this information before... here's a tidbit I'd like to add.
I read of a story where a mother from England visited France during her pregnancy. When the baby was born and as it grew older it understood French.
I can't find the story again but I think it helps prove your interesting point.
Now THAT's interesting. Maybe is just coincidence? I don't know, it's pretty weird. It seems that the article hints and affirms the idea of babies learning since they are in the womb hence it's so important to read and talk to our "bellies" even when we think nobody listens.
