Welcome to our CaringBridge site - we've created it to keep friends and family updated on Caleb's on-going struggles and compile all of our medical updates in one place.

Caleb is our adorable 7-year old middle child. He is a sweet, relaxed, and typically happy, go-with-the-flow kind of kid. He has a big sister Lilly (10 years old) and a baby brother Austin (1 year old), and a sweet service dog, Kip (a red golden retriever who is almost 3). Mom & Dad (Cassidy & Todd) have learned how to become caregivers and advocates, and are honing our nursing skills on a daily basis as we care for our medically fragile child. 

Caleb currently suffers from an extremely rare (less than 20 known to date) degenerative neurological condition caused by a mutation on his IRF2BPL gene. This condition has caused him to go from a typically-developing 2 year-old to a nonverbal, wheelchair bound 7 year-old with no gross motor skills, no fine motor skills, no ability to eat, or toilet, or do anything independently. He has a feeding tube and receives all of his nutrition and medicine via the tube. He has developed a seizure disorder. He has symptoms such as ataxia, dystonia, chorea, spasticity, strabismus (crossed eyes), reflux and vomiting, constipation, and occasional respiratory issues. This condition is, quite frankly, terrible. No one wants to see their child go through this. 

Despite all of the challenges, Caleb remains remarkably content. He loves his family, loves watching his favorite tv shows and movies, loves the pool, loves Disney World. 

Our medical journey to get to where we are today has been a long and tricky one (but honestly, given how rare his condition is, we are very lucky it was not significantly longer).
