The two things Lennon and Ono wanted most were to live permanently in the United States, and to have a child together. Their lives were stressful in the early 1970s for several reasons. There were the problems with immigrating to the United States, and with the search for Kyoko. The public were also sometimes negative toward Ono, her music, and her ideas. The couple had several miscarriages, caused partly by the stress.
