Car without Ac vents in back ?

Julii
Hello,
I live in Florida and this is my first baby. The past couple months since my baby has been born it hasn't been hot because of the rain and cold fronts. However, we are back to the hot humid days in Florida. I have a Toyota Camry and it doesn't have Ac vents in the back seat. It's not the first time someone is in the backseat of my car and complain that it's hot back there while the Ac is running.. I am considering in changing my car into something else that has Ac vents in the back so I can have peace of mind.. However, that would be paying a car for another 6 years. .. For the moms who live in Florida and have a car without Ac vents in the back .. What did you do ??? Please let me know. I am a first time mom and I'm freaking out because of the hot humid days coming ahead and I've heard so many stories of babies dying because of the heat. ☹☹😢😢
