Little sir, was born prematurely and spent his first 4 months of life in an incubator, and was diagnosed with Bronchopulmonary Dysplasia and Hydrocephalus caused by Periventricular Leukomalacia. Now is you're like me, you are compeltely confused by what you just read, don't worry I did some research. :)
"Bronchopulmonary Dysplasia (BPD) is a chronic lung condition that affects newborn babies who were either put on a breathing machine after birth or were born very early (prematurely)."-From Google
"Hydrocephalus is a buildup of fluid inside the skull that leads to brain swelling. Typically fixed with a shunt."-From Google
"Periventricular Leukomalacia (PVL) is a type of brain injury that affects infants. The condition involves the death of small areas of brain tissue around fluid-filled areas called ventricles. The damage creates "holes" n the brain." -From Google
Little sir, also has vocal chord paralysis due to prolonged incubation. I did some research on vocal chord paralysis, and it appears that every patient is different so I can't give you an exact explanation of what the side affects for little sir are.
Brendan sounds like an absolutely stunning little boy, having a family would enable him to make great strides in his progress, motor skills, and just in being adorable. Would you consider making little sir your son? :)
