The first is a cute shot; I would crop some off of the RH side to move the child out of dead centre, and use either the dodge or selective brush to try and reduce the under-exposure on her face (next time consider the use of a reflector, camera right). The other unfortunately has a badly exposed subject as your camera's meter was reading primarily the bright sky. You can probably improve it some in post, but you may reveal a lot of noise in the image. Next time call the child's name so that she looks toward the camera, and has a greater connection with the viewers.
Just my $00.02 worth - your mileage may vary.
