One of our friends has a 1 year old and wanted to bring the entire family to the game. She checked with the ticket office and apparently this 1 year old will need their own ticket. I thought it would be like airline rules where they wouldn't need a seat so no need for a ticket.

Has it always been this way? And also, why would we not want to make it easier to bring small kids to the game. It cost nothing and you get a kid raised with going to games. This is very short sighted / greedy.
