its a good camera, but i didnt know it took sd cards instead of CF cards, its not limiting just a bit annoying for me, especially if you plan on upgrading your body later to handle better lens. i think you will have fun with it. but like everyone else says it is a very very very expensive hobby. since i got my dslr last year I've already spent well over 2k in camera gear and plan on spending another 2k on another primary camera and some lighting. unless you plan to really be an enthusiastic hobbyist, you're better off with a higher-end p&s. because theres no point in spending well over a grand for equipment if you are never going to get out of auto or P mode, then that would just be wasting money, alot of it, and since you have a kid, thats already expensive. just a heads up. but since you already bought it...
congrats, have fun, take LOTS AND LOTS of pictures. and get out of auto and P mode.
