Not sure about that camera but it probably doesn't offer much control over exposure or focus, so I will give you some advice pertaining to composition only.
None of your shots are from interesting angles. They all look like you were standing in one spot turning around taking photos of things you can see without moving your feet. This is not how to do it, you have to move around and get up high or low or behind something or in front of something else to get an interesting perspective, or at least an angle that is flattering to the subject. With kids, it is best to get down to their eye level, and actually have them making eye-contact with the camera (in most cases, obviously somewhat dependent on the context). You have to watch the backgrounds, which you've actually done pretty well in most of your shots there.
