On Thursday, mom Ivanka Trump took to Instagram to prove this, posting a photo that shows just how much Theo's older siblings, Arabella and Joseph, adore him. "Observing baby Theo in awe!" Trump captioned the 'gram, which shows her two oldest children sitting at a table and looking at their baby brother, who is off-screen. Trump and her husband, Jared Kushner, welcomed baby Theodore on Sunday, but the mom hasn't slowed down at all. Hours before giving birth, she was spotted looking chic and polished while heading to brunch with Kusher, and two days later she returned home from the hospital in a spring-ready floral Dolce & Gabbana dress.
