She quoted in an interview, talking about her teenage days: "I had no time to fool. I didn't have any crush, I was busy swimming, riding, skating and doing radio plays on Akashwani, for which I was paid Rupees 10." When her elder sister died in a car accident, leaving behind two daughters, Kaushal decided to marry her brother-in-law, B. S. Sood, in 1948 and she set up home in Bombay where her husband was a chief engineer in the Bombay Port Trust. Her elder sister's daughters are Kumkum Somani and Kavita Sahni. Kumkum Somani has written a book for children on Gandhi's philosophy and Kavita Sahni is an artist. Kamini had 3 sons after 1955, from her marriage with B. S. Sood - Rahul, Vidur and Shravan.
