Another pleasant surprise

Yeah..finally DS can response to the song Twinkle Twinkle Little Star by opening and closing his small little hand. Been trying to teach him for so long that I nearly gave up coz whenever I sang this song..he will wave and juz smile..Errmmm Duno why? But to my surprise, I finally see him trying to open and close his hand when he was drinking his milk yesterday night. After that, when I sang to him and showed him the actions..He followed also..FINALLY!! Now trying to teach him clap clap hands..Hope he can surprise me with this action soon.
