Does repeated falling on the bed cause any damage?

My 11 month old nephew is trying to stand at almost any chance he can get. But the thing is that when he falls (he always does this on the bed) he'd land face first. He would quickly get back up, look around, and crawl to stand up again. Then he'd atumble and land face first yet again. I'm just worried that constant landing on the face/head, even if on a cushion like a bed, can cause any damage?Edit: Thanks for the answers. Just making sure my nephew is okay, I just want him to grow up perfectly healthy without any complications. I know tumbling is a part of growing, just having some precautions. via /r/Parenting http://ift.tt/2xeEnli
