As the article states, there were a few losses to the Kennedy family. She had lost a child in 1955, then the child mentioned here. The first did not reach the three month mark, and “Arabella” did, into the third trimester. When she started to experience bleeding, she had to reach John on his “boating trip to the Mediterranean.” As the article mentioned, advisor George Smathers convinced John to return to the US.

The third child lost was in August 1963: Patrick Bouvier Kennedy, who suffered a respiratory failure and died only 39 hours after his birth. John would lose his life in November of the same year.
