i found this list that id saved the link to before i had my op hun, courtesy of the gorgeous nikki198324
best bit of advice i had was to put everthing you need at waist level, its a nightmare when you cant do simple things like going into the top cuboard in the kitchen or hanging coats up on coat hangers lol
magazine
lip balm
front button or zip up top to come home with or a loose cotton vest that is easy to put on
sports bra
refreshing wipes
slip on shoes to come home with
mobile phone & charger
toiletries
i took a couple of tops to see which would be best suitable to come home with!
Pull on tracksuit bottoms
v pillow
throat sweets
