Hi there
Mum has been in her CH since Easter. I made sure she had several changes of clothes, i.e. trousers, tops, undies etc, slippers and her walking shoes (all marked up with her name and room number in permanent marker to avoid being lost in the laundry), toiletries, and something from home, in Mum's case a couple of her wedding photos, one with of her my Dad and one with my Grandad. Maybe a plant/flowers that she likes. I found the best way of getting her clothes in was by stealth, little and often. We also took a cuddly toy dog in, which she had at home. We found the little and often way of taking things in made sure she felt wasn't being moved in lock stock and barrel and she didn't ask why we were bringing things in. It took a while but Mum has settled there and is doing really well.
Good luck
Love Rosie
