SAN ANTONIO --  It's no secret. If you stepped outside Thursday you know it's a hot one across the Alamo City.

It's a time of year where we want to be sure we pay close attention to our elderly population and of course our children. When you're a kid at a splash pad, the hundred-degree temps are the last thing on your mind.

"Can't keep a 2-and-a-half-year-old in the house all day," parent Michele Smith said. 

Hundreds of San Antonio moms, dads, grandparents and visitors can't pass up a trip to Hemisfair Park.

"Yesterday we tried to do the touristy things, since my sister is here from out of state, but it was a killer. So today we knew we had to find something wet to get the kids cooled off and hanging out," parent Erica Snyder said. 

"This is really really nice. One of the best things in San Antonio," parent Rose Rodriguez said. 

As Texas continues to bask in the triple digits, doctors say places like the splash pad and the pool work just fine with sunscreen - but you still need to keep an eye on your kiddos.

"We have seen an increase in our ER visits for overheating. A lot of kids need simple things like hydration and a cool place to be. Fortunately, as of yet, people have been vigilant and we have not seen an increase in our ICU or serious heat stroke, but that's always a concern," said Dr. Ian Mitchell, trauma director for The Children's Hospital of San Antonio.

Mitchell said children need extra attention in this weather.

"They're particularly vulnerable because they're not as attuned to how they feel, they're not as attuned to their environment or what's going on. But also, physiologically, higher heart rates, more surface area makes them more attracted to getting too much heat too quickly," Mitchell said.

Children often forget or don't know when to drink water or how much.

Mitchell said parents should watch for signs like headaches, nausea, and especially if their kids stop sweating. He also recommends using ice packs to cool them down.

As for the Alamo City moms, they're making more game plans - from the splash pad to dry land.

"We stay in the house and drink plenty of water," Smith said.

"Kind of trying to do inside things during the day. We did the Doseum yesterday in the middle of the day when it was hot," said parent Lynn Spiers.

"We go to the library and do the library things indoors and other indoor things. This is the only outdoor thing that we do. Because it's too hot, but this is nice," Rodriguez said.
