My HV came over yesterday without making an appointment, when she got there, she found my partner downstairs washing the car and smoking, we live on the first floor. He took her upstairs and she took his height and weight. this morning i got a call saying she raised concern because my son was left alone upstairs and my partner was supposedly smoking cannabis, i explained to her that he left him upstairs because my son gets hyperactive when he is out due to his autism so its hard to control him when you are trying to do something else, and it was raining and cold so, he goes to check on him constantly, my son is the type that if you give him his ipad he will stay still for hours, my partner does not smoke cannabis he does smoke tobacco but we do live in a flat where other ppl smoke it which really doesn't bother me. My question is should I be worried? she was not even my health visitor she is someone we have never met before.
