Come to think of it, Little Nobba loves the sound of Daddy's voice too! Same as you, Min, bubs kicks a lot when Neil gets home from work and is telling me about his day.
I can't remember how many weeks I was when it first happened, but bubs also loves to move around when I am watching DVD's. I guess because the sound has more bass with the surround sound (unlike regular TV and videos). I got some great kicks when I watched Spiderman 2!!
