Ivanka Trump’s Older Children Are in ‘Awe’ of Baby Theo

Well, that’s a lot better than sibling rivalry.

Ivanka Trump‘s older children — Arabella Rose, 4½, and Joseph Frederick, 2 — are “in awe” of the newest addition to their family, little brother Theodore James.

“Observing baby Theo in awe,” the mom of three, 34, captioned an Instagram post she shared on Thursday.

Trump welcomed her bundle of joy on Easter Sunday and took to Instagram to announce the news with a message that shared the baby’s arrival date and time and also read, “Jared and I feel incredibly blessed to announce the arrival of Theodore James Kushner.”

While the family may have just brought the new baby home, Arabella has been excited about him for quite some time. In November, Trump revealed to PEOPLE that the 4-year-old told her whole class about her mom’s pregnancy before the entrepreneur had the chance to tell her family the news.

“My daughter makes me blush quite a bit. She reveals things about me in awkward contexts,” Trump told PEOPLE, before recalling the last time her daughter spilled the beans. “Probably it was Arabella announcing to everyone I was pregnant prior to me announcing it to even my family. Her whole nursery school class was congratulating me.”

Even if you don’t like her father you must admit that Ivanka is elegant and lovely. Her family is beautiful.

She seems like a great mama, and her two bigger kiddos look appropriately disheveled like all kids do in the morning. Joseph certainly favors his grandfather!
