The 30-year-old, who found fame on Nickelodeon as a teenager, admits she has been "reprocessing" her own experiences on the kids' channel, which she said are still evolving.
The star told a podcast children need more support and TV environments, "need to be made a lot safer all around".
When asked about what support child stars should receive, while being interviewed on the ‘Podcrushed’ podcast, she suggested that therapy sessions two or three times a week should be included in child stars' contracts to help them cope with their sudden exposure.
The star also said that parents should be "allowed to be wherever they want to be", suggesting that parents only "occasionally" came to set during her time at the channel.
Nickelodeon has been at the centre of multiple allegations of emotional and physical abuse by young actors.
Grande was just 14 when she first auditioned and starred on Victorious and she later starred in the spin-off show Sam and Cat.
