The `If It Makes You Happy` singer - who has two adopted sons Wyatt Steven, four, and 12-month-old Levi James - wants her kids to have a balanced diet but knows the best way to get them to be adventurous with their eating habits is to also give them their favourite treats.
She said: "I`m all about bribery when it comes to my little kids eating, particularly my four year old. `If you`ll try this, Wyatt, you can have some of this.` That-` how we do it."
The 49-year-old `All I Wanna Do` singer - who is currently dating Smokestack guitarist Doyle Bramhall II - admits she finds disciplining her children difficult, but was reassured by her mother that being tough on her sons wouldn`t upset them for very long.
She explained: "My mom said it`s going to hurt you a lot more than it`s going to hurt them.
"When I would get upset about putting him in a time out or being stern with him as Wyatt was going through the terrible twos and challenging threes, she would say, `Those things are not going to be memorable for him.`
"What`s memorable for him is gonna be the feeling of safety.-"
