Ivanka, who made headlines after over 30 retailers dropped her fashion line this month, told People that Joseph and Arabella have adjusted well to baby Theodore.

"My daughter is very independent, plus she's incredibly confident of her place within the home," Ivanka said. "So for her I was not too worried about the transition."

"I was a little more worried about [Joseph], he's very much a a mama's boy ... [but] he's loved it," Ivanka said. "He loves giving Theodore his bottle, he loves snuggling with us for books, he's always trying to kiss him."
