Oh, yeah, being out in public with a baby or small child is also just asking for unsolicited advice and disapproval.
Oh yes. I did come close to offering to give my youngest to the woman who thought she could do a much better job of parenting him.
I teach antenatal classes and remind the parents-to-be that they will be magnets for unsolicited advice and horror stories and to ignore the whole lot. I suggest that they smile if they can, but I might consider suggesting a large stick for when it all becomes too much. Maybe I could have a nosy-parker-beating-stick as the prize in my end of course quiz???
