Bad nanny question - I went to the park the other day, there was a little girl there the same age as my daughter, this little girl was being cared for by a nanny. The nanny was sleeping most of the time or talking to other nannies. I ended up watching this kid for almost three hours - I even fed her lunch! Ar one point I wanted to ask the nanny if it was ok if I gave her food and I couldn’t find her - I think she left!! I know the parents, but not well. Should I mind my own business or speak up?
