If you don't mind I will say why I suggested that crop.
Since the photographer is in control, the viewer tends to believe that enything that is in the picture is important in some way.
When an object is in the middle (like the baby's head) and there is empty space on one side, the viewer (subconsciously) tends to wonder why that space is there and why the photographer left that space and did not leave space on the other side.
Thus the space beomes an attraction - when it shouldn't be.
Space left in a composition should always be intentional - to balance something or to emphasize something because space is something and the viewer is aware of it.
By cropping some of the space on the right and the top, that smaller amount becomes less noticeable because it is just a safe buffer between the subject and the edge.
