Sylvester said the couple "made 100% sure Issy was insured to be pregnant, and any complications involving pregnancy whilst we were abroad were covered".

Sylvester explained: "Essentially what they said is that we would have been covered had the baby not survived. But the fact was that the baby survived."

"We weren't going to be covered for that, because we didn't put his name on the insurance policy."

As someone that wouldn't choose to travel into or through the United States, I can't say I would be surprised if I got back home after this ordeal and the medical bills started showing up. US healthcare will charge for anything under the sun. I half expect visitors will be sent invoices for travelling in the vicinity of a hospital in the near future.
