I think this fear goes in to everyone's heads somewhere.
My daughter was born a week overdue & was fine, a few hours later she was in ICU as she suffered a stroke.
Things happen that you didn't even know could happen, or things you've never heard of. Also things can go 'normally' & nothing 'bad' ever happens.
You could have a healthy baby then 17 years later he/she had something life changing happen & then they're disabled.
Whatever happens, you find a way to cope.
The anxiety is the worst bit. Trust me, I know that. Your brain likes to give you all sorts of worst case scenarios.
Also it's not as clear as to say 'can you put the baby in to care', you're forgetting that's YOUR baby. But if you're not a parent then I suppose it's easy to think 'That's ok, I'll just put them in to care should anything go wrong'.
I'm no preacher by the way, I didn't even want to hold my daughter when she was born, my maternal instinct if you want to call it that, kicked in only when she was wired up in an incubator & I couldn't hold her.
Pregnant or not, try to seek help for your anxiety.
