BABIES - CAN YOU LEAVE THEM AT HOME ONCE IN A WHILE?

Now I don't know what it is but parents seem to feel the need to take their babies wherever they go nowadays. Now I'm talking about little babies that aren't even a year old. Is it too much to get a baby sitter once in a while? Do you have to take your baby to a movie that I paid my money to see? Is the baby going to remember the movie? I think not! Do I have to dodge non-stop strollers at the Fair because you didn't want to get a baby sitter? Is a noisy concert the best place for a baby to be? Anyway, maybe I feel this way because I don't have kids but I really don't get why a lot of parents feel the need to take their babies everywhere they go. Just doesn't make sense to me.......
