    The softest fabric and the best sleep I’ve had in sometime. No more getting wrapped in my nightgown when turning over, the fabric in my ‘sleep warm’ is fabulous. I also bought the long sleeve short night gown, it keeps my arms warm while my feet are cool. I love your unique fabrics for the different sleep types….I never thought Eucalyptus as a fabric. I have given your ‘Mothers’’ set for a soon to be mother, she can nurse the baby with comfort and discretion.
