If your in Fort Worth you must take some time to go to one of the Cats games. This is a family friendly as it gets when it come to baseball. Tickets are very cheap and 3 and under are free!!! If you have a little one that won't sit through the whole game there are plenty of places to run around along with a bounce house.
Fort Worth's minor league baseball team is a blast to watch! Dodger, the mascot, roams around the ballpark and kids love to hug him and slap high-fives. There is a bounce house and huge sandbox/playground by third base that works wonders for any antsy kids who don't want to sit still for an entire baseball game. Check their website for any special promotions they might have with reduced price tickets. General admission is $6 and children under age 3 that don't require a seat are FREE.
