My son is 2 years old. He goes to preschool. I am looking for a lady who will take care of him three times a week. Twice a week, she will pick him up from preschool in her car around 1 PM, will put him to sleep, and will look after him until 7-8 PM. One day a week, she will need to be on standby at her home for 24 hours, as due to my work, she will need to take care of him for a few hours during the day, and sometimes she may not need to at all....
