Picture, Picture on the Wall

Can it be detrimental to hang family/kid photos around the house and in the kids' room? I heard someone say that too many individual photos of the kids can make them arrogant and think the world revolves around them. What do you think?

Figure it Out

How do you teach your kids to work out fights/issues on their own, without parental involvement? At what age should they be able to do this? Do you have suggestions for what worked for you, either as a kid growing up or with teaching your own kids?
