Savannah Chrisley calls Being a 'Bonus Parent' to Chloe and Grayson the 'Most Rewarding Job'

Savannah Chrisley loves being a "bonus parent".

The Chrisley Knows Best actress, 25, talked about taking on the job of parental guardian while her parents are spending time in prison in a photo collage she shared on her Instagram on Wednesday. "What my world spins around," she captioned her photo.

"I'm not their mom. I'm not their dad. I'm their sister and I get to love and guide them through life. Being a bonus parent is TOUGH...no one could ever add up to their parents," Chrisley continued.

"But these kiddos have shown me so much love, patience, grace, understanding, and appreciation!" she said. "Helping to raise these two kiddos is the hardest but most rewarding job I will ever have."

"I've always said, 'God meant for me to be a mama!'...little did I know, the journey would start a little sooner than expected! But luckily, I have had THE MOST AMAZING mama in the world to learn from! Because of her, I can do this!"

"Single parent/income households...I SEE YOU! We do it solo. IT IS HARD! It can be so defeating! But I promise you...God will NOT give us more than we can bare! I SEE YOU! I BELIEVE IN YOU! YOU CAN DO THIS!"

"Chloe and Gray...YOU ARE MY LIFE! Thank you for letting me love you and thank you for loving me back," she concluded the post.

Since becoming their primary guardian, Savannah has been sharing her experience parenting her relatives on her social media accounts and her podcast.

After her father Todd Chrisley, 53, and mother Julie Chrisley, 50, were given a combined 19 years in jail for tax fraud by a federal judge in November, the reality TV personality assumed primary custody of her brother Grayson Chrisley and niece Chloe.

Savannah started a podcast and has been posting on social media about her experience being the primary caregiver for her relatives.
