bunny17 I think you have it. My stepson went on Deal or No Deal to be in audience and they got specific instructions on when to laugh, clap, moan... oooh-ahhh. Yuck.
That said, we discovered that when our DGD plops down on her bum when working on her newly-discovered talent to walk, run and dance about, we clap and say YAY! Before that, these plops always brought on tears and since she was not hurt (low centre of gravity in play here), it appeared she was looking for a sympathy cuddle. To change that I clapped and cheered for her 'cleverness'. Then she clapped and laughed, too. Now she does it first... but not so much now as she's found her feet. I am waiting for her to clap and cheer if I fall over LOL!
