I used to be a brownie leader, so I know a lot of kiddie songs :) My favourites are "Alouette" and "Rainbow Connection". I also go to a weekly baby songs group, and I've learned a few more silly songs with actions for young kids. There's a lot on YouTube, if you want to learn some yourself.
But today she also got a rendition of Queen's "Bicycle Race" when her bicycle diaper cover came up, and all the verses "American Pie" when it came into my head when she was fussy. Oh, and what I remembered of a couple songs from Carmen with silly voices.
What can I say? I get bored narrating my day but I still want to expose R to language, so she gets a lot of mama singing.
