On June 5, 2018, Duff welcomed her second daughter, Lulu Gray Rosenberg, into the world.
“She arrived June 5th, and brought all her magic with her!” Duff shared joyfully on Instagram. “Ryan is the happiest big sister & we are finally a family of 4! Meet our littlest one… Lulu Gray Rosenberg!”
As a food blogger, Duff expressed her contentment with having two children.
“Truthfully, we really wanted another girl,” she mentioned in a 2018 interview. “Ryan could have that bond of sisters.”
In a separate discussion with Morning Honey, she offered her perspective on balancing work and motherhood.
“I am still trying to figure it out. I fly by the seat of my pants most days, trying to make sure that I am there for much of my kids’ activities and things like that,” she explained. “I try to outsource – I try to have a lot of help.”
She added, “My kids are always going to come before work stuff. If I ever have the choice between going and doing something that is a volunteer thing for my kids’ school or something, my work stuff is just always going to be pushed back because of it, and that is probably not always the smartest thing, but I have that mom guilt that I think most moms have.”
