I like kids and not only tolerate them, but actively enjoy them. Some little snot waves at me, I wave back. If they want to chat for a minute, that's fine. Larry and I have been known to share our food with kiddos at the next table (with their parents' permission, of course). And I will watch my language if there are little ones within range.
But those are nice little kids, not screaming, misbehaving hellions who need their ass beat. If some squab comes wandering over to my table, I'll say hello to them. But Mom or Dad better come retrieve them within 30 seconds. And PS, make them sit down in their seat.
Some kid kicking the back of my seat is a no go. And a tantrum throwing nuisance will get a nasty look, and perhaps a comment or two, thrown their parents' way.
Let people see the best in your child and admire them as they deserve. Don't let them see the evil spawn that lurks within. Keep that part to yourself.
