Anything new about the "superbaby"?

Liam Hoekstra, a.k.a. Superbaby. Born with mutated genes for myostatin production, giving him hyper-developed muscles. All the links I can find are at least a year old, so I was wondering how he’s doing. Is he suffering any health problems related to his unusual developement?

P.S. on review, I’m not sure if there was more than one such baby in the news. I thought one was supposed to be German and Liam lives in the US.
