Although I am very respectful, and always dismiss myself if I have to sneeze or blow my nose, or anything of the like. However, I actually pay little attention to other people at other tables, other than to scan for the shooter, and babies seldom, if ever, show up on my radar. Most are well behaved, and even most kids are as well. If I'm at a car show, I would not even pay attention to a baby, unless I was introduced to one in conversation. If someone wants to bring a baby, or change a baby, it's none of my business and I am not offended in the least. Heck, sometimes I wish I could just go when and where I want to, it sure would be handy!
Now dogs?? I go out of my way to meet as many dogs as the owners will allow. Dogs are a true measure of a person or situation, they are very acute to their situation and surroundings, and often can alert to danger before it starts.
