Night potty training

Hey girls, my baby (3yearsold) is fully potty trained during the day. It’s the nights that are now difficult. When she has a bath to go bed she says she is “dirty” putting a clean nappy on to sleep, so that’s a fight in its self. She falls asleep In her bed but ends up in my bed. (Accident ready on her bed but not mine)( also a single mum so my bed is just for me but happy for her to be in bed with me). What is the best suggestion for “potty” training at night?
