Playing womb sounds to your baby may help them sleep but, I’d advise not doing this on modern technology devices like cell phones, iPads or tablets as this can harm you and your baby. Use an old fashioned tape recorder or a cd player on a bureau near by. I’ve included a nice womb sound tape that lasts a long time. There are others. Howbever, this one in particular, I found very relaxing.. Below please examine the info on how to protect yourself and your baby.
