My friend came round last week with her 4 month old baby. When they were at mine, they had a pretty bad fall (mum was holding the baby so both fell). It was on a bit of floorboard that I know needed replacing as it wasn't stable.
I walked in front of my friend and avoided this bit of floor, then turned around to warn her but she'd already stepped on it and they'd fallen. She landed on her back and baby landed on top of her.
They got up immediately, my friend said she was totally fine and baby was totally fine, no bleeding/no marks or anything and they both then stayed for our planned lunch etc. Baby and friend both happy, friend repeatedly reassured me they were fine.
Friend texted me when she got home again re-iterating they are fine.
It's now a few days later, I haven't heard from friend (not unusual, we don't talk every day). But in another group chat we are both in, another person shared some good news a few hrs ago and everyone except my friend has replied.
AIBU for 1) 100% blaming myself for them falling because I didn't replace the floorboard and didn't warn them about it and 2) panicking that something has developed since I last heard from my friend and they're in hospital suffering latent effects from the fall????
