I am looking for a babysitter in london to provide care for my nephew, who is autistic and non-verbal. he enjoys food and may need assistance managing his eating habits. while he is generally well-behaved with new people, he can wander off if left alone, so close supervision is important. he also engages in sensory behaviors, such as slapping his stomach. the job involves providing support on july 28th, during my wedding from 2pm to 7pm. there will be a children's playroom available for him, and he can have screen time on a tablet or phone, which will be provided, to help him stay calm. this is a temporary position for a total of 5 hours, and i would appreciate your help in ensuring he has a comfortable experience.
