Jadwiga was childless for over a decade, which, according to chronicles written in the Teutonic lands, caused conflicts between her and her husband.{{sfn|Halecki|1991|p=245}} She became pregnant in late 1398 or early 1399.{{sfn|Halecki|1991|p=252}} Sigismund, King of Hungary, came to Kraków in early March to negotiate for a campaign to defend [[Wallachia]] against the Ottoman Turks.{{sfn|Halecki|1991|pp=252–253}} Vytautas, in order to bolster his authority over the Rus' principalities, decided to launch an expedition against [[Timur]], who had subdued the [[Golden Horde]].{{sfn|Halecki|1991|pp=256–257}} According to [[Jan Długosz]]'s chronicle, Jadwiga warned the Polish noblemen not to join Vytautas' campaign because it would end in failure.{{sfn|Halecki|1991|pp=256–257}} Halecki says that the great number of Polish knights who joined Vytautas's expedition proves that Długosz's report is not reliable.{{sfn|Halecki|1991|p=257}}

On the occasion of the expected birth to the royal couple, Jogaila's cousin [[Vytautas]], [[Grand Duke of Lithuania]], sent expensive gifts, including a silver cradle, to the royal court on behalf of himself and his wife, [[Anna, Grand Duchess of Lithuania|Anna]].<ref>{{cite web|url=http://www.muzeumhistoriipolski.pl/kalendarium/8/zmarla-jadwiga-krolowa-polski-wywiad-1399-7-17.html|title=Interview about Queen Jadwiga of Poland|access-date=23 December 2011|author=Jadwiga Krzyżaniakowa|language=hu|archive-date=2 April 2012|archive-url=https://web.archive.org/web/20120402214023/http://www.muzeumhistoriipolski.pl/kalendarium/8/zmarla-jadwiga-krolowa-polski-wywiad-1399-7-17.html|url-status=dead}}</ref> The first horoscopes written for Jadwiga's and Jogaila's child predicted a son in mid-September 1398.<ref>Ozog, pp. 135, 322</ref> However, a girl was delivered on 22 June 1399 at [[Wawel Castle]].

The newborn princess was named Elizabeth Bonifacia ({{langx|pl|Elżbieta Bonifacja}}, {{langx|lt|Elżbieta Bonifacija}}), after Jadwiga's mother and Pope Boniface IX who, in a letter of 5 May 1399, had agreed to be godfather under the condition that the infant be called Boniface or Bonifacia. She was baptised by [[Piotr Wysz Radoliński]], [[Bishop of Kraków]].<ref>Wdowiszewski, p. 250</ref> However, the infant died after only three weeks, on 13 July 1399.{{sfn|Frost|2015|p=91}} Jadwiga, too, was on her deathbed. [[Stanisław of Skarbimierz]] expressed hope that she would survive, describing her as the spiritual mother of the poor, weak, and ill of Poland.{{sfn|Brzezińska|1999|pp=407–408}} She advised her husband to marry [[Anna of Cilli]], Casimir the Great's granddaughter{{sfn|Halecki|1991|pp=264–265}}—which he did—and died on 17 July 1399, four days after her newborn daughter.{{sfn|Frost|2015|p=91}}{{sfn|Halecki|1991|p=257}}

Jadwiga and her daughter were buried together in [[Wawel Cathedral]], on 24 August 1399,{{sfn|Frost|2015|p=91}}{{sfn|Halecki|1991|p=257}} as stipulated in the Queen's last will. On 12 July 1949, 550 years later, their tomb was opened; nothing remained of the child's soft cartilage.<ref>Olbrycht and Kusiak, pp. 256–266.</ref>
