The legal guardian of 23-month-old Charlotte Wyatt failed yesterday to delay a court review of the order allowing doctors not to resuscitate her.
Mr Justice Coleridge ruled at the High Court in London that "Charlotte's interests demand that this matter be looked at urgently" and said the review should go ahead on the 13th and 14th of next month rather than in November.
Huw Lloyd, representing the guardian who is appointed by the court to look after Charlotte's interests, applied for a postponement because the guardian is involved in a child abduction case next month.
Mr Lloyd said she had developed a "good relationship" with the parents, Darren, aged 33, and his wife, Debbie, aged 24, and he claimed it was "essential" that she should be at the High Court review hearing.
But David Wolfe, for the parents who are originally from Birmingham but now live in Portsmouth, Hants, said Charlotte had made " astonishing and remarkable" improvement but his clients were concerned that a delay in the review of the girl's treatment would mean that she would be exposed to the onset of winter and the danger of respiratory infections.
When Mr Justice Hedley made the High Court order he said it should be reviewed next month when Charlotte will be two years old.
Last month her parents lost a Court of Appeal bid to overturn the order but the appeal judges said the review should be heard in October over two days rather than the two hours envisaged by Mr Justice Hedley.
Doctors at St Mary's Hospital in Portsmouth won the legal right last October not to resuscitate Charlotte after arguing that her brain and other organs were so seriously damaged she had "no feeling other than continuing pain".
But Lord Justice Laws, one of three appeal judges who dismissed the parents' challenge to the order, said his court "attached a high importance to the up-to-date position being properly investigated "with a view to a decision on whether the order should not continue".
