Yolanda Hadid is going to do everything in her power to make sure her children live a happy and healthy life.

The Real Housewives of Beverly Hills star has been very open about her battle with Lyme Disease since her diagnosis in 2012. However, she's been a little more reserved when it comes her two youngest children, Bella and Anwar Hadid, who she only recently revealed are also struggling with the illness.

The mother-of-three took to Instagram to share some insight on how she's trying to help them fight the disease early.

"I will walk to the end of the earth to find a cure for my babies so that they can live the healthy life that they deserve to live," she captioned a picture of three vials of low dose allergy medicine that help strengthen the immune system.

Yolanda revealed the bombshell news of her children's diagnosis while accepting the "Power of One" Award at the inaugural Global Lyme Alliance gala in October.

"When my two youngest children, Bella and Anwar, were diagnosed with chronic Lyme disease in early 2012, watching my babies struggle in silence in order to support me in my journey struck the deepest core of hopelessness inside of me," Foster said while standing at the podium. "No child should suffer the way that you do."

Meanwhile, Yolanda is also battling more than just health issues right now. Last week, E! News learned the reality star and her music producer husband, David Foster, decided to file for divorce after four years of marriage and a total of nine years together.

"Sadly we have decided to go our separate ways. We've shared nine beautiful and joyous years together and during that time we experienced love, friendship, and the inevitable challenges that come with managing a marriage, careers, blended families and health issues," the couple told us in a joint statement.

"We are grateful for the years we've spent together and believe wholeheartedly that we did our best. I hope that we can pave the road ahead of us with all we've learned and with the love and respect we will always have for one another."
