Yep SS if you dont already have a play gym then I think you should get one. In my honest opinion I believe the play gym taught Georgia so much ad she used it from birth to right up to only a couple of weeks ago and it is portable so you can take it to friends/relatives houses etc. The only reason we have put it away is that she has started to stand and hold onto the couch etc. We got the fisher price one its a jungle theme - its the one with a giraffe on it you wont miss it. We got it at big w. It plays forest sounds, or just music and it has lights. You can also set it so that she has to tap the play gym or the toys to get the music to go. When Georgia was a newborn we used to just play the music on constant for her then as she got a little older we set it to the tap mode and she worked out really quickly that she had to make it work herself. You can change the toys hanging from it all the time and it has a mirror on it aswell and Georgia used to love catching sight of herself in it. She also has a mobile over change table and this is the other thing that I believe taught her heaps so keep it where it is.

Singing the ads is a great idea, I dont know if it was listening to so much music when I was pregnant or the fact that we play alot of music in the car but Georgia started to dance (she sways her top half) whenever she hears music it is so cute. Music is good for them I think.

Good Luck
