Talking about singing to your babies... Just sing and don't worry about the 'quality' of your singing!
I am always a music lover and I have so many CDs of different types of music at home, varied from disco pop to serious classical pieces. Since I have my baby boy 6 months ago, no joking, I suddenly became an "automatic singing machine" whenever I'm with my son. I just can't stop singing or huming melodies to him. Sometimes I even have to remind myself to TALK rather than sing to him. I sing many different songs to him, depending on my mood; but there are some songs I keep singing to him over the last 6 months. I can see he now can recognise some of the songs coz' he'll show a big smile when I sing those familiar songs. And, I realise when I introduce a new song to him, he will become very attentive to my singing. It's so nice to see these interesting reaction from your little ones. The latest one I sing is "How Much is that doggie in the Window".. Cute!
Cara: Coincidently, "You are my Sunshine" is also one of my favourites.
