If you saw a woman begging on the street with a 3 year old boy over a period of days, would you eventually call the police?

On my way to work, I’d see a woman with a young boy, presumably her son, begging for change with a sign that said “Stranded. Please Help”. She was out there for about 3 weeks, child with her the whole time. Do you give a woman down on her luck the benefit of the doubt and do nothing or do you call the authorities on behalf of the child’s well being?
