I'm a newbie trying to learn how to use a new camera. Today I was tinkering around with settings and whatnot (as I do daily) and tried using the "sports" setting to get a shot of my daughter zipping around the living room with her baby stroller. I've taken countless shots of her using the flash, but it doesnt really depict "movement" and seemed rather boring to me. The shots I got today were somewhat puzzling. The background was really blurred (in a movement type way) but she was completely out of focus in every shot I took. I know I focused on her...so I'm not sure what I did wrong. Maybe I needed to be further away or maybe there wasn't enough light??? Perhaps the DOF was too shallow? Any help would be grately appreciated. I'm trying to get a "first steps" type of photo since she should be walking on her own any day now.
Here's a sample of what I'm talking about.
