It is so difficult to get ethical approval in research studies involving infants, that I'd imagine the risks were suspected to be minimal, but there isn't even a title to this project yet so I doubt theres enough evidence either way (then again it would have been terminated long ago if there was the slightest ounce of harm, so its probably going better than you think... guess we'll have to wait til he publishes his work to find out).
