Have you seen this commercial? Aside from 3 in 1 plus 1, this is the other commercial that makes little Gwen stare at the television. Whenever she sees it, she would really focus on it (this is aside from the fact that I sing to her the lyrics).

I, too, love this commercial. I can relate to it. Our house is small which just enough for the three of us. When the little girl grows bigger, she will definitely sing it to herself... I just hope that she won't act that way :p
