Any suggestions?! I really wanna start playing a song for my baby everyday that when he or she is born I can play it for them and it'll soothe them or even help them sleep !! Any nice baby songs. Like from a Disney movie or whatever . My sister in law did the song "once upon a December" from the movie Anastasia but I can't copy that lol
