3 weeks ago, we lost the youngest member of the family. Olivia Mae was 2 years old when she passed away unexpectedly.
I say unexpectedly, even though she had been quite sick. I say unexpectedly, because you just don't expect a 2 year old to die. I say unexpectedly, because she had made some great progess in the last 6 months or so and there was no indication that anything was seriously wrong.
Olivia was born with a condtion called Hydroencaphaly. Basically, part of the brain does not develop (properly or at all) and is replaced by cerebral fluid. In Olivia's case, this was a direct result of having suffered a stroke in utero. There really is no explanation as to why this happens. There 'may' be a genetic component but even that is not quite proven.
