In a recent conversation withPureWow, the actress and mother of two revealed that “The guilt that I felt for bringing her into the world was so big” considering Luca had been an only child for six years.
“It was just he and I for so long that he was like, ‘Why?Why, Mom? Why would you do this? I really just love the way it is,’ ” recalled Duff, 32. “And it wasn’t bratty, it was just so sad.”
Afterlearning she was pregnant, theYoungerstar remembers asking herself, ” ‘How do I reverse this?! It’s too late now.’ It’s such big feelings. When you’re pregnant, everything just feels more magnified.”
But Duff knew things would be okay once Banks actually made her arrival. As she told PureWow, “He came in after I had her. Iwas just holding her, and the look onhis face was an absolute shock. He just said, ‘That’s my sister!’ And he had to sneeze, so he ran out of the room and was like, ‘I’ll be right back.’ He let out this huge sneeze in the hallway and said, ‘I had to sneeze and I knew I couldn’t do it in here near her.’ ”

Now, “It’s the best,” Duff said of the dynamic between the two siblings. “It’s a chemical reaction between siblings sometimes where he knows he has to protect her.”
Once in a while that protection can be so intense it actually needs to be dialed back a bit, according to the mother of two. In November, Duff told PEOPLE Luca has beenkeeping an extra close eye lately on Banks— to the point where he’s scolding his mom!
“He doesn’t want her to ever fall off the couch … sometimes I’m like, ‘I swear I’m a good mom,’ ” theLizzie McGuirealumna said. “He’s like, ‘Well, you need to watch her.’ ”
“I’m like, ‘She’s gonna fall down. She’s got to learn not to go near that’ or whatever,” she continued in her conversation with PEOPLE. “I sat him down once and said, ‘Hey, you survived and I was your mom, so I swear she’s going to be okay.’ ”
