My sister was born when I was 12.  The first three or so months, she cried a lot.  We found out later there was a reason for it (other than the general brattiness that she retains today) but during those times I remember I’d hold her and dance around the living room, listening and singing this song:

I still love this song and to this day can’t hear it without thinking of those days, dancing around, trying to get my sister to shut up.

It still hasn’t happened.
