By 1861, Sophia had given birth three times in three years, and after this her health was frail. The same year she made a trip to Nizza to cure her health, and she continued to make trips for health reasons. The next trip was made in 1863; this time to Germany. In 1864, she engaged in the building of their summer residence Sofiero by Öresund, which was named after her. In Sofiero they could remain in contact with the Danish royal family at Fredensborg on the other side of Öresund. The gatherings at Sofiero would sometimes be given a political dimension as the center of family councils.
