I just can't see why, after inputting the notes electronically (the majority of which seem to have been scribbled by another nurse) you wouldn't immediately get rid of it. And if you did accidentally take it home, why wouldn't you dispose of it the minute you realised what you'd done? She'd just moved house too, it's not like there was junk everywhere. Her texts to her friends also said there was no spare bed yet so unless it got moved (again, why?) that makes me think it was her bed. Unless it turns out LL was also a secret hoarder, I can't see this as anything other than a trophy/momento, just like the card to Baby I's parents that she kept a picture of on her phone.
