My godson, Charlie, is 4 months old and he's a beautiful little boy, I adore him

He's my best friend's son - some of you will probably remember when she lost her little boy, Kyle, to cot death 3 years ago.
He had to go to hospital today, as he's got a blockage outside his bladder. They scanned it and said on friday he has to go back and have dye injected inot his bladder (which is going to be so hard for Hannah to watch) so they can see the blockage better. They think it's a lump, probably a cyst, but what if it's not? Either way they said he has to have surgery next week to fix it, as soon as they can book him in to the childrens hospital.
It's scary, I know I couldn't bear to lose him, it must be a hundred times worse for Hannah.
I'm sorry to make a fuss on here, it's just in RL I have to be strong for Hannah but it's hard not to worry. I'm seeing them tomorrow (we see each other three times a week usually to look after Charlie and her baby brother together, cos her mum works so I babysit).
