1892–1930: Early married life
From the time of their engagement, Aino and Sibelius had talked about getting a house of their own in the country, and had looked for a house near Lake Tuusula as early as 1898. When Sibelius's wealthy bachelor uncle died in July 1903, they bought about 2.5 acres (10,000 m2) of land in Järvenpää near Lake Tuusula, using Sibelius's share of his uncle's estate to pay the architect. Lars Sonck was chosen to design their house, which they called Ainola. The Sibelius family moved there in the autumn of 1904, having borrowed a substantial amount of money to buy the land and build the house.
Aino's early years in Järvenpää were stressful and difficult, caused partly by financial worries and partly by her husband's drinking and partying lifestyle. She sought to eke out the family budget by creating a vegetable garden from the stony ground near the house. Aino homeschooled her daughters, a task which she performed very successfully, since they all did well when they later went to school. She spent a period in 1907 convalescing in Hyvinkää Sanatorium.
In 1908 her husband had a throat operation and gave up alcohol for almost seven years, and this was the start of Aino's happiest years. Margareta was born in 1908, then Heidi in 1911 (when Aino was 40 years old), and the children all grew up in Ainola – the only time they lived elsewhere was during the Finnish Civil War in 1918 when they had to move to Helsinki for a couple of months.
