Princess Estelle, Duchess of Östergötland

She was baptised in the family's antique baptismal gown, which was first worn by Prince Gustaf Adolf when he was baptised in 1906.

Her name and date of the baptism were added in embroidery to the gown.

On the date of the baptism, a limited-edition prayer book titled Princess Estelle's Prayerbook (Swedish: Prinsessan Estelles bönbok) was released and published.

Princess Estelle is second in the line of succession to the Swedish throne and the first female in Swedish history to be born with a right to inherit the crown that cannot be superseded by the birth of a male heir, as well as the first person in Swedish history to be born of a female heir apparent.

The only two princesses of Sweden to be born first in line for the throne were heir presumptive at their birth: Christina (who eventually became queen regnant) and Hedwig Sophia (who was superseded by a younger brother).

As second in line to the Swedish throne, she has been in the public eye since birth.

Princess Estelle of Sweden, Duchess of Östergötland (Estelle Silvia Ewa Mary; born 23 February 2012) is a member of the Swedish royal family.

She is the elder child of Crown Princess Victoria and Prince Daniel, Duke of Västergötland.

She is the eldest grandchild of King Carl XVI Gustaf, and is second in line of succession to the Swedish throne, after her mother.

Estelle was born to Crown Princess Victoria and Prince Daniel at 04:26 CET on 23 February 2012 at the Karolinska University Hospital in Solna.

The birth was greeted by two 21-gun salutes on the island Skeppsholmen, opposite the Royal Palace in the capital Stockholm.

Her names and title were announced on 24 February 2012 by her grandfather King Carl XVI Gustaf at a cabinet meeting.

After the cabinet meeting, a Te Deum was held in the palace's royal chapel.

Prior to the official announcement of her name and title, an error resulted in the royal website displaying the incorrect name and title – Ulrika Marianna Annika David, Duchess of Upplands Väsby, which was later removed.

The staff eventually revealed the reason was that they were testing the system.

Estelle was baptised on 22 May 2012 at the Royal Chapel of Stockholm Palace in Stockholm, Sweden.

Archbishop Anders Wejryd conducted the ceremony.

Her godparents were her maternal uncle, Prince Carl Philip of Sweden; her paternal aunt, Anna Westling-Söderström; King Willem-Alexander, the then-Prince of Orange; Queen Mary of Denmark (for whom she was given her fourth name) then crown princess; and Crown Prince Haakon of Norway.

On 17 May 2014, two-year-old Estelle inaugurated a fairytale path, named in her honour as "Duchess Estelle's Fairytale Path" in Tåkern, Östergötland.

At the time of her christening, she was presented with a miniature swan and certificate to the trail indicating that in the future she would perform official engagements there.

She also visited Linköping Castle, where she was received by Elisabeth Nilsson, Kristina Zetterström and Ann-Catrine Hjerdt, the mayor of Linköping.

On 25 August 2014, Estelle started preschool at Äventyret Preschool in Danderyd Municipality, Stockholm.

She started to attend the Campus Manilla School in Royal Djurgården in August 2018.

Estelle's full title is: Her Royal Highness Princess Estelle Silvia Ewa Mary, Duchess of Östergötland.
