Hello all - have not read to catch up. Just checking in to say that we had an amazing time in Kenya, truly FANTASTIC - highlight was a wild giraffe eating out of DS's hand 
Unfortunately on the penultimate day he got something called rotavirus which he could have caught anywhere (most common cause of D&V in the UK) and he got dehydrated, we were admitted to the Nairobi Children's Hospital who were wonderful and got him hydrated and back up to speed. We flew home, all was well for about 4 days and then he started having all kinds of terrifying symptoms - nosebleeds in his sleep, waking up covered in unexplained bruises, a pinprick rash that came and went, spiking fevers, spots that are not chickenpox and finally blood tests showing abnormal liver function (we are still waiting for hepatitis test results).
We're pretty sure now that he developed something called ITP where his immune system mopped up the first D&V virus and then instead of ramping down, started attacking his red blood cells. Nothing to do with travelling to Kenya, nothing they can do - he just needs to get over it on his own. Doctors have been pretty useless - every scary symptom they treated as something on its own (kids get bruises, kids get nosebleeds, kids get rashes/spots, kids get fevers - yes but what about ALL AT THE SAME TIME!) Low point was when the pediatric consultant told us he needed to be tested for leukemia - DH and I had to then have The Chat about what we would do, who would quit their job etc.
Anyway he's made a definite return to health - still tiring easily and is very pale and still bruised, but eating like a horse again and running riot through the house. Today's my first day back at work - last two weeks I've had off as compassionate leave taking care of him as he literally would not be put down and was so sad and listless and sick that it was heartbreaking.
It's been the most terrifying two weeks of my life but every chortle and belly laugh and mouthful of food that goes down his little throat is like the best thing that ever was.
Ok, now to read and catch up with everyone!!
