Smiling in his heart
Our son Ryan smiles with his heart because he is unable to move his facial muscles. Most of the time, a lack of smile can be mistaken as a sign of unfriendliness or being unapproachable but in reality people with Moebius Syndrome wear their smiles broadly across their heart.
Ryan's sixth and seventh cranial nerves in his brainstem never developed and do not function. This leaves him unable smile, grimace, frown, blink his eyes or move his eyes laterally.
