A recent photograph of the nearly 5-year-old girl with a binky in her mouth has sparked debate about how old is too old to be using a pacifier.
Representatives for Cruise and Holmes did not respond immediately to requests for comment. But Holmes has spoken in the past about Suri's determination to do what she wants.
"She picks out all of her own clothes and has since she was 1 1/2," Holmes told New York magazine last year.
"I'm happy that my daughter is strong-willed and determined," she said. "You really have to go with what the child is wanting."
Not too long ago, Cruise and Holmes were criticized for their daughter's designer taste in clothing, ranging from a Burberry coat to specially designed Christian Louboutin kitten heels. Before that, they got flak for allowing her to suck away on her bottle past the age of 2.
