Hi there
I'm also in the UK and my daughter also was born with Tetralogy of Fallot.
The only difference is: She was born at home and until she was 5 months of age: no one knew.
If you have any questions you want to ask, feel free.
I made an educational video about the condition and it's on Youtube - it's that good, I've had medical students congratulate me on the good job I made of it.
I wish you both the very best of luck, we're all here for you. x
IF you look at my youtube you'll see my daughters journey through it all, Part 1, Diagnosis. Part 2, surgery and part 3 her first birthday, they are incredibly emotional videos - so only watch if you're feeling strong, it's always an emotional time, your daughter will be fine, I of course, can't guarantee it (wish I could) but the medical advances mean that once these children were expected to pass away basically from suffocation, can now have surgery and live totally normal lives. xx
