Street photography with children??

I for myself are photographing since 20 years now. Since half a year I'm making street and documentary photography in urban space quite intensively (mostly with the cell phone camera because of it's flexibility).
A great question in street photography is nowadays: how to deal with photographing children, or photographing scenes with children?
Children are not only nice picture subjects, they are part of daily and urban life. A longtime street photography project without children in the pictures wouldn't be complete, I think.
However, my important premise is with all my photographs: no posting of pictures at the internet. I'm doing photography only for myself, pictures are at most showed within my closest family, without digital spreading.
But nowaday's problem when photographing children is the fear of many people or parents what would be going on with the pictures in digital space; it is even possibly to be confronted with the police as a street photographer in such a situation. Also, the situation is aggravated when you are a male photographer instead of a female one.
The people can't imagine that a photographer takes pictures only for taking pictures - they can't make a difference between photographing and posting pictures online. They don't understand that to photograph is not the probem, but showing the pictures online! That is a development that's really absurd. Look at pictures of Roger Mayne, Vivian Maier, Helen Levitt: it is really sad that making such pictures is suspicious or even criminalized today!
Because of all that I'm a little bit cautious with child photographs (although there's nothing to accuse to myself). I'm not interested getting in contact with the police because of false suspicions through other people.
My question to all you street photographers: did you ever have a confrontation with the police when taking pictures of or with children? Or did you even got a house search from the police with taking away your digital devides because of street photography and a false suspicion ?

Thanks very much for your answers...
