Simon Ndungu Kinyanjui and his wife Margaret Wangui have lost their quintuplets who were born at the Nakuru Level 5 hospital.
Family members confirmed the babies' deaths while speaking to journalists outside the hospital.
"It's unfortunate tumepokea ripoti and that sio za kufurahisha but hatuna kitu cha kusema coz tu God yeye ndo alitupea na yeye ndo amechukua so it's well," Simon's sister Monica Kinyanjui said.
Monica added that they got news about the deaths of two of the babies in the morning before they were informed at around 1 pm that the other three also didn't make it.
"Tulipata news about the two kwanza tukaenda nyumbani unfortunately around 1 ndo tumepata news kuhusu hao wengine," she said.
Margaret's sister Leah Nyambura Wangui said the deaths of the quintuplets was hard for them to deal with. She noted that the babies' parents were deeply affected that's why they couldn't address the media.
"Ripoti tumepokea kitu saa saba kua watoto wote wamepumzika but ni God's will. The father is not around hangewezakufika hapam it's so painful to believe. Na pia mama pia kwake ni ngumu ju venye alikua amepokea watoto wake," Leah Nyambura Wangui said.
The family further asked well-wishers to stand with the couple and offer them any kind of assistance - more so employment.
Bahati Member of Parliament (MP) Irene Njoki, who visited the couple at the hospital, also mourned the deaths of the quintuplets.
"A sad ending. Rest in Peace (RIP) to the five angels," Njoki wrote on Facebook.
The lawmaker was among those who visited Simon and Margaret in the hospital and gave them basic essential goods for the babies.
The five babies were born preterm weighing 500 grams. Consequently, the hospital's medical team placed them under incubation.
Speaking to the press on February 1, Samuel, who is a matatu tout, stated that he did not expect his wife to deliver five children.
He asked the public for assistance to cater for his babies.
