Trying I am sorry to hear about your DGS and I am sure you will be really worried but I think you will see the best of the NHS. Clinically and for the most specialist services it is second to none, it is just under incredible strain. Where is he going to be treated? Paed cardiac services are highly specialised and highly centralised; the standard expected of those units will be very high indeed.
As some of you will know I was a senior manager in the NHS until I stopped last year to be with my son more. Same from that angle as your experience Blue - I was working 60-70 hour weeks routinely, plus on-call management responsibility for a major acute multi-site trust (when on call I would get called a lot!). Easter 2015 I had a big deadline on top of my day job and for about 2 months I was working in excess of 18 hour days, including most weekends (and Easter itself). I was utterly delirious with exhaustion. It was only when I passed that deadline that I had the time to really look at my DS (then not quite 3) and I realised I had been too busy to properly notice his issues (ASD). I was devastated and so guilty that work had prevented me seeing it sooner.
Unfortunately I can't see the situation in the NHS getting any better as resourcing can't keep up with demand. There is a workforce of over a million people most of whom are working in an unsustainable way. I know so many good people, clinical and admin, who just can't keep doing it and are leaving 
£20 top up in Waitrose today. Ocado is coming tomorrow but I needed bits for dinner tonight as duster is unecoevtedly staying, and I also wanted to bake a cake to take to BIL and SIL tomorrow morning when we go to see new nephew with the terrible name
SIL is gluten free so I have made a suitable lemon drizzle cake involving mashed potato
. BBC good food recipe, got good reviews though. Mine sank a bit but even the picture in the BBC site is somewhat concave so I think that is normal?! Not terribly impressive to look at and seems excessively moist so might be Destination Bin instead.
I also bought a cute outfit for the baby nephew and can't find it. I have been sorting through DS's old stuff and have had some girl clothes donations for our baby too so I am literally drowning in tiny vests etc. Can't see the wood for the trees!
Love the dog pics.
