They requested their husbands to go and break her "pativrata" vrata (being loyal to husband all the time).

They went to Anusuya as guests when Atri was not there at home and asked her to serve them food (lunch) without wearing clothes. She agreed and remembering her husband put the water on their converting them to 3 babies. Here the 3 goddesses were waiting for their husbands to come back and eventually arrived at the scene to find that their husbands have been converted to babies. They repented and by the request of Anusuya the three Gods decided to be born as her 3 sons.
