It's definitely a photograph of a statue, if you go to the large version, you can see that it is cracked through the neck. I do think you are on the right track that it is religious in nature, but as far as it being an Andrea della Robbia I don't see any similar to yours. I do think it's probably a depiction of Christ as a child, the posture certainly gives that impression, but I don't know what the significance of the wrappings might be. Possibly something about rebirth from the trappings of death?
