Re: Visiting new babies etiquettes...
i'm one of those parents .... if i see someone putting their finger in my son's mouth (it has happened, you will be surprised how many people do it and see nothing wrong with it), then yeah, my guard is up and i tell them to wash their hands. fortunately, most of the time, i have not had to do this.
if anybody is travelling on public transit, the same expecatation is there. wash your hands. especially with all this swine flu business, public transit is a very quick and easy way to pick up all sorts of germs.
you would wash your hands anyway when you come home right and hopefully before eating anything with your hands? so you can wash your hands before touching my kid or sticking your finger in his mouth. now he has teeth so think again cause he'll bite. :D
