Carey, who welcomed her twins in 2011 with husband Nick Cannon, said she tries to do everything on her own but requires extra help to fulfil the needs of her kids, reported Contactmusic.
"Every little bit of a child's life counts, every memory, every moment. I can never have this time back. But it's a luxury to be able to have someone there. I don't know how people do it," Carey said.
"I did everything I could, but I couldn't have done this without extra help. I'm grateful. I have two people who help a lot," she added.
