I have exactly the same situation as you......the only difference being my sister was stillborn in 1962.
I contacted the GRO to see whether I could obtain a copy of a certificate but was advised that only the parents named are able to do this. I will be able to once my parents have died (horrible thought).
I cannot discuss my sister with either of my parents, they have just blocked it all out and prefer to leave it that way. Very sad.

The reply you got from the GRO is not actually correct.
The GRO policy is that only the parents of the stillborn child may ask for a search of the stillbirth register and purchase a certificate but the law says different.
In law each application is actually dependent on the decision of the Registrar General.
It is possible that the Registrar General would be willing to accept an application from a sibling and direct the GRO to provide a certificate.
This has been done many times in the past the current guidance simply speeds up the situation by not having to forward every application to the Registrar General.
Try writing to the Registrar General and explain the situation, stress the importance of being allowed to find closure on the loss of your sibling, a loss which though it happened years ago is very significant to you as a sibling. Stress also that the present guidance is actually causing more anguish fed by the fact you feel you are having to almost wish for the death of your parents before being allowed to know the truth about your sibling.
The 1953 Act section 30/3 states-
(3) The foregoing provisions of this section shall not apply to certified copies of entries in registers of still-births, but the Registrar General may, if he sees fit in any particular case and on payment of as aforesaid of the appropriate fee aforesaid, cause a search to be made for, and allow any person to have a certified copy of any entry in any such certified copies or in any filled register of still-births which has been forwarded to him.
