Can a baby in the womb hear other babies cry?

then be prepared to go crazy. babies cry. alot. thats what they do. its their way of communicating with us to tell us that they are in need of something. but no, i dont think your baby will be affected by this little girls crying and it certainly wont damage your little baby in any way, but maybe u should consider not baby sitting anymore if the little girl does your head in so much, maybe u r not up 2 it?
