Bell opened up about raising 4-year-old Lincoln and 2-year-old Delta with ET on Monday, offering a quick piece of advice to other moms of toddlers. 

"The one finger rule was something I really enjoyed," she confessed. "They said, 'Let your toddler experience things.' Like, 'I wanna touch that vase!' Rather than always saying, 'No,' you say, 'Let's do it! Let's do one finger.' So, my toddlers go around and touch everything with one finger."
