Julia loves it when we sing to her, even though neither of us sing very well. Before she goes to bed, I sing one to her while we're rocking in our chair and she usually conks out to sleep then. My favorite to sing to her is "La la lu" from Lady & the Tramp and Bart's favorite to sing is "Au Clair de la Lune". He says his father (who passed away when B was in his teens) sang it to him as a kid. Which ones do you sing to your kids?
