Little Big Town singer Kimberly Schlapman's mother Barbara Roads now requires '24-hour care' two deacdes after being diagnosed with Parkinson's disease.

At first, the 56-year-old country crooner 'didn't think much of' the tremor her 78-year-old mom developed, but the degenerative neurological disorder has progressed.

'No one in our family, to our knowledge, has had Parkinson's before,' Schlapman told USA Today on Saturday.

'We didn't understand what her care would mean. We didn't know enough about the disease to know where we were headed. But now, I mean, it's 24-hour care.'

The Over and Over singer has her hands full raising two daughters - Daisy, 18, and Dolly, nine - from her 19-year marriage to stage manager-turned-second husband Stephen Schlapman.

'I love being a mama. I also know what my mama has meant to me in my life. And so now I get an opportunity to care for her. That's incredibly important to me,' Schlapman noted.

'I also have a job where people rely on me.'

The Georgia native recently relocated in order to be closer to the former school teacher, and she's also hired help to pick up the slack between relatives.

'I just wouldn't have it any other way,' Schlapman said.

'We're very, very involved in her care and with her doctors, and there's one of us at every appointment she has.'

The AbbVie paid partner kept Barbara's condition a secret for many years, but she now realizes 'there is no shame in this disease.'

'And there are so many of us out there living with it that we need each other and we need to talk about it,' Schlapman said.

'And the more we talk about it, the better off our loved ones are going to be because their care is going to be better and people are going to understand it more.'

The Hey There Sunshine singer continued: 'I want people to know they're not alone in this disease. Whether you have the disease or your loved one has it, there's so much to advocate for.

'And this disease is so complex that talking with a doctor and being open and honest about every single little or big symptom, every challenge, every change is so important so that your doctor can help you find a treatment plan that meets your needs as best as possible.'

Little Big Town is next scheduled to perform this Thursday at Harrah's Stir Cove in Council Bluffs, Iowa.

The three-time Grammy winners' 12th studio album It's a Dying Art drops on August 28.

The Nashville singing quartet - founded in 1998 - also features Karen Fairchild, Phillip Sweet and Jimi Westbrook.

Little Big Town pulls 4.3 million monthly listeners on Spotify, and they've sold over 4.5 million albums worldwide.
