Aww, this must have been a very special experience indeed :) Btw I´m glad to hear that the mother didn´t abandon them after the worker got so close to the nest, you know, animals do that sometimes when disturbed by humans. In your previous post, I told you that I haven´t seen baby pigeons but I just recalled that many years ago, when we lived in a tall apartment building, a couple of kestrels built a nest very close to our windows and there even were babies in there later on. We used to watch them like this too, although not from such immediate distance. It´s like real life National Geographic :)
It will be a memorable event for the kids for sure.
