That's fascinating to me, coming from the UK, that you could be well enough off to be able to afford a decent amount of help with the babies but not (or barely enough) for IVF. My IVF to have twins in the UK cost about the same as 4 months of nursery fees!
I often overheard convos with my mum to godmum. She (gm) went to Nigeria for cheaper IVF, and they put 5 male embryos in, if I recall. Wasn't successful and was almost fatal for her.
So even though this story is wild, I'm almost not surprised.
