Early life

Srirasmi was born in Samut Sakhon Province to a family of modest means. She was the third child of Aphirut () and Wanthanee () Akharaphongpreecha. She has a total of four siblings.
She attended college at Bangkok Business College. In 1993, at the age of 22, Srirasmi entered the service of Vajiralongkorn as a civil servant in charge of "waiting on him". Srirasmi enrolled in Sukhothai Thammathirat Open University in 1997 and graduated in 2002 with a bachelor’s degree in management science. Vajiralongkorn personally bestowed her with her diploma. In 2007 she received a Master of Arts degree in Home Economics from Kasetsart University.

Marriage and family

Srirasmi married the crown prince on 10 February 2001 at a private ceremony at the prince's Nonthaburi Palace. The public was informed of the event some time afterwards. The prince, who had married twice before and has children with his previous wives, stated it was his intention to settle down: “I am now 50 years old and think I should have a complete family.” After the wedding, she was styled Mom Srirasmi Mahidol na Ayudhya (Mahidol is the surname of King Bhumibol Adulyadej and King Ananda Mahidol, whereas na Ayudhya signifies an indirect line, i.e., she was 'married' into the family).

On Valentines Day, 15 February 2005, it was announced that Srirasmi was pregnant. On 29 April 2005, a healthy son was born via Caesarean section at Siriraj Hospital, named Dipangkorn Rasmijoti.
Because of the birth, she was granted by King Bhumibol Adulyadej the title "princess of Thailand" and style "Her Royal Highness" as the royal consort of Crown Prince Maha Vajiralongkorn. A royal ceremony, called "Phra Ratchaphithi Somphot Duan Lae Khuen Phra U," to celebrate the first month of the baby was held on June 17 2005 at the Anantasamakom Throne Hall in Bangkok.
Princess Srirasmi initiated and launched the "Sai Yai Rak Jak Mae Su Luk" (Love and care from mother to children) campaign which promoted breast feeding.
