Well its proven that babies can listen to sounds while in the womb. I had a gala time catching up on all my TV shows and I watched an overdose of Friends and Big Bang theory while I was pregnant.
The miracle occurred when my baby would kick or move everytime the Friends theme would come on. Maybe I imagined it then but till date my now almost 11 m old son leaves all his toys and is transfixed to the TV when the Friends title song plays! Proof lies in the picture!
