Remember Gavin Arvizo? The boy with cancer (who had his treatment paid for by MJ) (also who MJ allegedly molested but that's beyond the point).
The kid went through aggressive chemotherapy for months when he was just starting puberty, at the age of 12 and still had a growth spurt through it. If the stress of cancer, chemotherapy, impending death at a young age doesn't stunt growth I doubt a little sleep loss would.
Gavin Arvizo looks like he grew to be at least 5'7.
Which is pretty impressive, considering the fact that his mom looks about 5'2, and you know, the fact that he had cancer and chemotherapy throughout one of his most vital growth periods. I really doubt he would've grown any taller had he not had cancer.
