Juvenile myasthenia gravis (JMG) is a rare autoimmune disease affecting the neuromuscular junction in children and adolescents. Its clinical presentation is usually associated with ethnicity and pubertal development. We present a 14 month old patient with, bulbar symptoms and a good clinical course. The age of onset in this case is lower than average and the case is in pharmacological remission after medical treatment. Prepubertal JMG is very rare during infancy in Caucasians and ocular symptoms are more common in prepubertal patients. This Caucasian case is uncommon since she has presented with bulbar symptoms and early onset.
