There is still some uncertainty why Sam's sodium went up so high, and it is still slightly higher than is normal, but there are a couple of theories - last week Sam stopped vomiting (day AND night) which was fab, but maybe this is why his sodium had risen as it hadn't been expelled. The other theory is that possibly his gut is absorbing more nutrients than first thought.
So we've been sent home with TPN that has had the sodium and trace elements altered and have to take Sam in to the local lab for blood tests on Saturday. We have a follow-up appointment on Monday at hospital, where he is also due to have kidney/bladder ultrasound and a dental appointment!
Off to unpack in time to get to school to surprise the girls - they've had such a fab time with their cousins that they may be disappointed the inpromptu holiday is over!
