Jacob Lopez and his brothers are second-generation allergy sufferers.
"They have a cross between what I have and (what) my husband (has)," said Jacob's mother, Veronica Lopez.
According to allergist Dr. Erika Gonzalez-Reyes, if one parent has allergies, the kids are 30 percent more likely to have them.
If it's both parents, the chances go up to 60 percent.
And if you live in San Antonio, the risk is even higher.
"They did the skin testing and they figured out that his skin testing was so severe, that he should do allergy shots," Lopez said.
The primary treatment for combating allergies is avoidance, but with active kids like Jacob, it's not very realistic.
Gonzalez-Reyes said there are new nasal sprays on the market.
"Recently, there have been newer nasal sprays being launched some with combination anti-inflammatories and anti-histamines, which work great at controlling the symptoms," Gonzalez-Reyes said.
The big three are Ragweed in the fall, Mountain Cedar in the winter, and Oak in the spring.
"When we have those really robust winters with a lot of rain, which we did this past year, and then our warm weather kind of quickly follows that, our trees tend to pollinate earlier and they also tend to pollinate in larger quantities," Gonzalez-Reyes said.
