my baby loves to sing!, I swear she was singing straight out the womb! literally, she would make little sighs and purs. As of late, it's "old McDonald had a farm" that she loves! which makes sense because she loves animals!!! without fail, when someone sings old McDonald had a farm she sings e i e i o, and when she wants to sing the whole thing, she sings (with the right tune) BO BO BO bo BO BO bo, e i e i o. it is hilarious!, and I must say.. she is quite delicious right out of the bath!
