Last year 43 children died in hot cars across the country, and according to AAA, Texas once again led the nation in these tragedies, as it has for the past 20 years.

Just last week, a 7 month old child died in Eagle Pass after authorities say the father forgot to take her to daycare before heading to work.

Jennifer Rodriguez with San Antonio Police Department said it's a tragedy we see too often nationwide.

"It just takes seconds for something to happen," Rodriguez said. "A child could also get locked in a vehicle, someone can come steal your vehicle."

Rodriguez said putting an item such as a purse or a briefcase in the backseat with the child could also help remind parents to double check.

"These situations are extremely tragic and you don't want to put yourself in a situation where your child is left in a vehicle that is hot. It takes just a few minutes," Rodriguez said.

Now, carmakers are also introducing new technology to help parents keep their children safe.

Stuart Laggerson with Cavender Buick GMC North in San Antonio said GMC's sensors alert drivers to check their back seat.

"Anytime that you've opened the rear doors within 10 minutes of starting a car," Laggerson said. "There are a lot of parents who are out there that do have multiple kids, do have lives and family... many times they forget - not necessarily a child, but a briefcase or something that you need for the day."

Several other car companies are now also offering this feature and there's a push to make it mandatory in all cars.
