Ivanka Trump steps out looking incredibly slim a WEEK after the birth of her son - as the family take him for circumcision ceremony

She only gave birth a week ago, but Ivanka Trump looked incredible as she dressed up for her newborn son's bris in New York on Sunday. 

The 34-year-old's third child with husband Jared Kushner - named Theodore James Kushner - was born on March 27. 

They also have Arabella Rose, four, and a boy named Joseph Frederick, two. And in keeping with the couple's Orthodox beliefs, baby Theodore is to be circumcised in a ceremony, also known as a brit milah, on the eighth day of his life.
