    Terry and Dean:
    We are so sad to hear of Kayleigh’s death.

    There are no words of condolence that would be sufficient except that we understand first hand your pain and know that it will be with you forever.

    We will make a donation to ORSA in Kayleigh’s memory, although we prefer that it be anonymous.

    Remember all the joyful positives and you will know that her life has been worthwhile.

    Dear Terry, Dean and family,
    When John and I heard the news our hearts felt broken. We remember Kayleigh so fondly from those many early days of ORSA and family get togethers. She was always joyful and our daughter Jessie just loved her Rett buddy! Terry and Dean were the definition of dedicated parents, nothing was spared, everything was for their precious girl. She was an inspiration to many. We were blessed to know her.
    All our love The Lidsles.

    Dear Terry and Dean, and family,
    With a bit of a delay, we were shocked to hear of the sad news of Kayleigh’s passing. We understand first hand how it feels, the pain of her sudden departure, the emptiness of life without her, the vanishing of so many dreams. May her many accomplishments despite huge limitations be a constant reminder that her life was an true blessing. You can be proud of what you have done to her and to so many other people affected by Rett Syndrome. Her memory will live on in our hearts.
    Agnes and Joseph
