It was just three months after the Russian invasion of Ukraine in early 2022, but Marwa Yehea wanted to return to her home in Kyiv.

Ms. Yehea, 31, who is originally from Syria, had fled the Ukrainian capital with her two daughters that February when the war began. In those early days of uncertainty, she was pregnant with her third child, and they spent weeks in Germany.

But she was determined to be back home by the time her son was born. By May 2022, they had returned to Kyiv in time for his birth.

“The war hasn’t ended, and the psychological toll that takes is tiring,” Ms. Yehea said during an interview in Kyiv this summer. “But you get used to it. And us especially, as Syrians who emerged from war — well, here we’re secure.”
