When you have a CTR 5 and a daughter who will be a sunbeam next year, you can use all the help you can get. Anne Bradshaw has a contest going to give away a free "Tiny Talks" book. Go to her website to find out how you can enter too.
My son hasn't yet given a talk in Primary. The one time he was assigned last year, we were all sick that weekend. I'm not sure he would have stood up in front of everyone and talked or not. But I am pretty sure he'd do it now. He gets nervous doing new things, but he'll usually try new things when his mom is by his side.
