When I was about 6 months pregnant, my husband and I made a cd of Led Zeppelin songs to listen to on a long drive to my parents' house. Being the typical man that he is, he has to listen to his music as loudly as possible. When the song "Cashmere" came on, David turned it almost full blast, and I started to feel my baby go absolutely WILD. For my delivery, we brought our Bose radio and a mix cd of relaxing songs to listen to while I was in labor. After my son was born, I sung "All of my Love"-also by Zeppelin, to my son, and I swear to you, he smiled. Now, whenever he has a hard time falling asleep, I pop in a little Led Zeppelin on his crib cd player (these are amazing...and they don't get very loud at all, nice and soothing for baby), and it puts him right to sleep.
