Maybe Queensland redbacks are more potent than West Australian ones? My biological father was bitten by one, and he just felt a bit off. Perhaps we're built of sterner stuff over here? As to childbirth, the only time I felt woozy was when I tried gas (nitrous oxide, I think) - horrible stuff! John says childbirth didn't hurt a bit...
John's Mum was bitten by a tiger snake - she stepped off her back step straight on top of it - it wrapped itself around her ankle and bit her twice. It was touch and go - she had 3 lots of antivenine plus either platelets or plasma to help the blood to clot. Can't say she's ever been the same since...
