Childminder for 13 and 16 year old girls overnight. 6 nights a month

My wife of 16 years passed away on the 16th November 2025. She was only 50 years old. I have 2 daughters aged 16 and 13. I work shift and work 6 twelve and a half hour night shifts every month. Two nights together at a time .I need someone to just stay in the house over night with the kids. No cooking, no putting them to bed. Someone to just stay overnight while I am at work. I will be back home at 8 am in the mornings.
